There are many companies working on this type of technology at the moment. We made ours in 2018, and Chad visited my house in January 2019 to film most of this. We didn't post it for various reasons, but decided now might be a good time. The fidelity of the inference is a function of how you train it.... so obviously the more data points you provide, the better it will perform. This particular type of machine learning is known as object detection, with the computation being performed by a deep neural network "on the edge". The video stream is processed locally and no internet is needed to find the object in real time. If you're working on something similar or could use this technology in your systems and would like to collaborate....

Do me a favor and PLEASE CONSIDER SHARING THIS VIDEO. I'm a bit worried it won't be distributed due to images in the video and the topic in general.... but I believe this is a positive thing and it's something people on both sides of the gun debate can get behind. I've been talking to people about this type of technology and in an upcoming video I will explain how this is simply one component in a much larger suite of tools which can be used. Are there flaws in this method? Absolutely. Is it possible to spoof a system like this? Yes... this could be easily tricked.... but would be perps would have to take the time to worry about it focus on tricking it. I personally think the main benefit is providing real time situational awareness. Another limitation is that it would identify toy guns as real guns and send a notification to authorities. The purpose of this video is to start the discussion because systems like this are frankly already here and in use. We don't claim to have all the answers, but we decided to use our engineering skills to try to make a positive step. We've found support amongst both sides of the gun debate, and in today's political climate that alone feels like a step in the right direction.

Something like this that can not only tag a video feed, but present a paper trail of video feeds, that's invaluable and ingenious. I love this idea!

[@shauntoochaos235]

We had about 120 feeds. We had a person shoot them selves on site and only knew that we had an "active shooter" after the police got there and one of the guards had to ask what was going on. (While the guy had shot himself and no one else we didn't know that at the time) an automatic notification from cameras would allow for lock downs to go into effect much quicker.

Not wrong. I would be curious, in maybe 5 years or so, about how machine learning is going to be used to identify common attributes of mass shooters. We are using it here to identify an active weapon, down the road I think it's obvious this will be used to profile/identify certain traits. I'm not saying that is a bad thing, I'm just raising an eyebrow at the idea and wondering how crazy this sort of tech will go.

[@albinkarlsson8998]

totaly agree. very well done

[@masasuka]

The polarity is on whether we should ban guns or not, as Destin said, everyone can agree that gun deaths are bad, and the number of gun related deaths should go down. I think this tech is a great start, but the implementation will be limited, and I think the biggest opponent to its implementation will be the same as what Destin was talking about with the company that is developing the mass IR/x-ray system that will detect concealed weapons, Privacy. So my question to go along with this, if Destin is still looking, how does this differ, privacy wise, do these other technologies, you're still implementing a sort of big brother system that will constantly monitor, and detect incidents that you are teaching it, how are you planning to get over the whole 'my baby shouldn't be filmed all the time' thing that a lot of people, understandably, will voice as a blocker to getting this in schools, malls, and other public areas?

[@JoJirgens]

I am by no means an expert but I have just finished writing a thesis on object detection using deep leaning algorithms and I can see some possible issues in your training data set that could possibly be causing some performance issues. Namely a lot of the training data seems to be high quality images taken close up to the gun which I don't think properly reflects the kind of images you would get from a security camera. Security cameras are generally low quality, positioned at a high angle and it is unlikely they would ever get such a close up view of the gun. Perhaps some artificial training data augmentation such as randomized down scaling, brightness and contrast adjustment and image rotation could help make the detector more robust. The image down scaling may improve the ability for the network to detect the gun when it is relatively far away, but something I found in my project was that the relative size of the object in frame also had an effect on performance. The objects i was detecting were anywhere from 20-100 pixels in size so I implemented a system where the input image is sliced into crops run through the detector and then stitched back together and it massively improved the performance. however it does lead to slower processing times as the network has to run multiple times per image so it may not work as well for your real-time application. Anyway, you may have already thought of these things but I thought I'd put them out there just in case you hadn't. Really cool project though, interested to see where it goes in the future.

[@Jimbodawg]

Very solid points, something along those lines crossed my mind when watching the video but I wasn't sure about how the technology could be improved to combat against video degradation. Maybe gesture tracking, combined with deep learning a large set of hand motions commonly used when handling firearms, like how the tech in video tracks finger placement but on a broader, more animated scale.

[@Nicksperiments]

I think the best solution is get higher resolution cameras. Like 1080p NVR cameras instead of the potato cams they usually have

[@JorenMathews]

Why would cropping the image into smaller images help? You're still running the same # of pixels plus you risk chopping the object you're looking for in half and making it unrecognizable.

[@arsenymakarov6961]

I guess the real shipment ready solution should include multiple differently trained algorithms that work at different levels of intensity (in terms of processing power required) and have levels of alarm. For example one trained to find a person in stress that turns on the other network that gets a crop of that video feed and tracks more closely to see some other signs of potential violent behavior and if triggered the next network gets cropped up feeds of each hand and looks for a gun. And probably I'm missing some stuff that needs to be looked for.

"Did you tell them what you were doing?" "Yeah." "And they were all on board?" "Yeah." Sums up the stance of gun owners on gun violence. The idea that those who treat guns as a hobby or occupation are somehow in favor of gun violence is mindblowing and idiotic.

[@drops2cents260]

I beg to differ, because there are (simplified) three types of gun owners: responsible, negligent and malicious. There's nothing wrong with the first group, of course, but there is with the latter two. And because of the latter two, _sensible_ gun laws and restrictions for ownership are a necessity because of the "well regulated" part in the 2nd Amendment. That's why I think that things like e.g. psychological evaluations and background checks should be mandatory - because in my opinion, gun ownership should be _both_ a right _as well as_ a privilege: first, you should be required to _earn that privilege_ by proving that you _can be trusted_ to act responsibly and are _competent_ in gun handling, safety etc. - but as soon as you _prove to be trustworthy and competent_ , you _must have the right_ to own them.

[@lx5tgp]

@@drops2cents260 Yeah, I guess we'll just ignore the fact that ridiculously thorough background checks are already a nationally mandated requirement for purchasing a firearm.

[@fxzn]

@@drops2cents260 background checks are already mandatory, there is a 30 day waiting period for your gun, you cannot buy a gun if you have any violent criminal record. you do get a psych eval along the process too.

[@JWPSmith21]

@@drops2cents260 The only problem with the psychological test, is deciding where to draw that line. Say someone doesn't trust the government, or believes that they might have to use that gun to fight a tyrannical government. That could so easily become unacceptable, and then anyone who wishes to own one for that reason can't. I've tried finding a solution for that, but haven't been able to come up with one as of yet. I agree, there should be a psych eval, not even just on the owner, but all occupants of a home. Another issue with this, is that the psych eval must be free. Otherwise, it's unfairly taking away the ability to on a gun from poorer populations, namely minorities. They would be the ones who would have to defend themselves from a tyrannical government more than other groups. It's those without the power who would be abused, not those with it after all.

[@drops2cents260]

@@JWPSmith21 > The only problem with the psychological test, is deciding where to draw that line. Of course, and that's true for psychological test in general. But a line has to be drawn who should be allowed to own guns and who shouldn't. So the point is not if such tests should be mandatory or not, but to carefully design and evaluate them so the line gets drawn at the optimal position. And when in doubt, I sleep much better if one person might not be able to own a gun who would be a responsible gun-owner than one person owning a gun who shouldn't. Because when it comes to things which are dangerous (and guns are), I prefer to err on the side of caution and prudence instead of taking risks which are completely unnecessary.

[@alexlandsbergs]

I disagree, I think its too gimmicky. 1) easy to bypass, cover the gun with a cloth or something and the cam cant catch it. 2) most likely the system is to slow to prevent any casualties. even if it was instant and 100% perfect at detecting a gun. by the time it either allerts security or sets of an alarm, the shooter most likely has already shot at people. which, the gun shots themselves would warn everyone in the area what is going on faster than the alarm. 3) like he said about the more in depth system being too invasive of privacy, that would be whats needed to actually stop anyone like this. and systems like that are too easily abused.

[@kumd]

I just don’t see anything special here. Also once a shooter pulls out a gun, I’m pretty certain everyone in the room would know before the software does. The argument that the police can find the shooter with this is kind of irrelevant too, gun detection system or not they could just monitor the cameras and easily find the shooter. As brutal as it sounds, if I was an investor and or buyer I would pass on this too. Unless it had some under clothes detection technology to prevent a shooting from happening in the first place, it’s really nothing special. Also, anyone that knows or has written in Python could easily make this program using OpenCV. Item detection software can sometimes take a matter of hours to make and it’s honestly not that complicated if you use a prebuilt framework like OpenCV.

Well if the guns already in your hands chances are they're going to start firing immediately. Have you ever seen cop footage? The second the gun is out the person with it starts shooting every time guaranteed, unless it was a robbery. It's redundant. You will already be aware if they have a gun by the fact they'd be shooting or the fact you can see the goddamn gun. I understand if it's like at an entrance of a school or something, but what's the point in warning about that then? Think about it this way. Almost every single school I have ever seen or been to the cafeteria is right next to the front Entrance. A wide open space where a lot of people gather. The gunman can go from front door with gun drawn straight to shooting at masses of kids in the span of seconds. So what's the point in the system? For the other kids? They'd know before the warning because you could hear the gunshots. This isn't gonna go anywhere. There is no point.

How do you think it is that we came to live in a world where information-handling companies are so motivated to collect this data? As to who follows the laws, the government doesn't either. Could it be that government pressure years ago to collect, aggregate, and provide access to user data has left us today with a tech industry with similarly skewed ethics? If you require a group of people to do unethical things, the people with integrity will leave the group over time. Their positions will attract people who are most comfortable being unethical in the particular manner that's required. It should be unsurprising.

[@RemX405]

Having worked with object detection myself and computer vision, I can tell from experience that it is very easy to get a proof of concept "working" like this one, but extremely difficult to make it a viable working product. There are so many problems I can already tell just from this video: 1. You trained your algo on movies with cinematic angles on guns, but you want to detect guns on security camera footage, where the angle is wide, far and from above. I'm 100% sure it won't detect anything on low res security camera footage since you didn't train it in the conditions you want it to work. 2. The program is a frame by frame detector, not an actual video footage detector. You got no "frame over frame tracking" that could help with those false positives. 3. The amount of false positives is way to high. 4. Even with the impressive amount of data you got, it can't even detect the gun at several angles, point blank at the camera in near perfect conditions. 5. What about other types of guns ( other than handguns ) ? It's a neat trick, but that's it.

[@ButchWilson]

I wouldn't denigrate it as a "neat trick" because it isn't. A trick, that is. It is a beginning. The discussion and the video indicate that it isn't close to ready for market. And, as indicated, it isn't intended to be a "one size fits all" solution. BUT, you bring up some avenues that would help. For example, if they could use actual security camera footage -- and gain access to law enforcement live training videos -- to increase the sample data for the machine learning, that would help.

[@FredDufresne]

I agree with almost everything you said. The only thing I disagree with is that it's a neat trick. Everything else you pointed out is definitely a problem, but they all have a clear and existing solution. 1. Higher resolution cameras 2. Use surrounding frames in the model 3. More training 4.

Know this was a joke, but I (like I assume most engineers) have a compulsion to analyze --if they're detecting it on a given deck, they know where it is, they're just filtering the report for the captain's ears. While the captain's managing 3 hull breaches, thruster failure, and navigating through a debris field while engaging 4 Romulan BOP's, the fact that the sensors picked up a firing arc between spatial coordinates (1,3,5) and (3,5,7) in compartment 4 (or in the hall outside) of deck 11 is probably not an appropriate level of granularity for verbal communication. The full staff on the bridge micromanages so that the captain can make the big decisions. Also, he can access info on the chair-arm displays in front of him, so most of the verbal communication is to make really sure he's aware of a strategically salient event.

Quite honestly, if an active shooter is using a backpack or a bag to camouflage his gun, there's a very good chance that whoever he was firing at is going to survive and/or get away. Especially with smaller caliber bullets like those fired from a pistol, a backpack could very easily distort the bullet's trajectory enough for the victim to at least retain their life.

Also taking into consideration that they're a relatively new issue, yet the US has had not only the 2nd Amendment the whole time, but also again firearms used to be LESS restricted than they are today. If access to guns was the main or only large factor, this would have always been an issue and just as, if not more, common than it is today in the past. Also, to suggest that the only difference culturally, politically, socially, etc between the US and Japan is firearm access is absolutely absurd.

[@mechanicalman1068]

@@jqpublic9777 restrictions don’t necessarily infringe on ones right to “keep and bare arms.” First, just as all rights come with responsibilities (which may take to the form of mandatory safety training, safe storage or even liability insurance), no rights are absolute (you can’t take a gun in to a court house. You can’t take a gun in to private property without the owner’s permission. Felons generally can’t own guns.) Second, there are only seven people in the world with the authority to define what the constitution means, and neither you or I or anyone else here is one of them. These concepts have been affirmed and reaffirmed by the courts again and again.

[@YZFoFittie]

Yeah but not trigger discipline...

[@Tralin]

@@YZFoFittie I noticed that too, though a couple of things come to mind: - The gun was demonstrably unloaded - The muzzle was pointed in a safe direction - This experiment would need many different levels of testing, finger on, finger off, held normally, held upside down, slide back, slide forward, etc. Although I agree that trigger discipline is incredibly important, science does demand that we occasionally change how we're doing things. It was great to see Destin do it safely, even if it's not what you'd expect.

[@macebobo]

@@Tralin the gun was not "demonstrably unloaded" at 6:17 - 6:24 and in the video thumbnail, I agree that the AI may need what you note, however, trigger discipline was not even mentioned in the video.

@@macebobo They brought up safety, and previous content from Destin has shown he's a safe handler. Do you really need every shot in every video to have a "Okay, we're clearing the gun now" before proceeding? And not every rule must be mentioned at all times. How about licensing? Did he show he is allowed to own one, or even hold one? Should every video containing a gun start with the parties handling the firearm by showing they have the correct documents?

So one interesting thing about computer vision algorithms like this is their inherent bias based on how they were trained. Y'all touched on this a little with the comment that you needed "lots of different hands". This is a subtle point, but super important to think about when deploying algorithms like this so that you don't end up with "racist" or "sexist" algorithms. This is a big deal in many applications of machine learning and something we think about a lot as computational biologists where these algorithms are increasingly being applied to diagnostic and prognostic predictions.

[@noahchristensen7342]

I know you're probably joking, but you probably can't. Not just because Google wouldn't give it to you if they had it, but Google most likely doesn't even know how the gun detection algorithm works. The algorithm is trained from images of guns instead of traditionally programmed. The engineers don't even do very much (if not none at all) programming on the actual behavior of the algorithm, so they don't really know how it works.

[@LilBigHuge]

@@noahchristensen7342 I'm sure their algorithm is capable of explaining itself and how it comes to the conclusions that it does but even if it doesn't your argument still makes so sense. If you upload a video with a gun in it youtube will catch it and mark it or flag it or label it in whatever way. Now if you simply applied the same analysis to live footage then it should do the same thing. Also this may already be a thing because the algorithm may work with live KZbin videos already.

One thing that seemed to be missing in your training of the image detection was lower contrast - like a black gun in a black glove in front of a black jacket.

[@Z6D4C4]

Good luck with getting that to work.

[@ericjx]

I imagine this would be nearly impossible with visible cameras. Maybe if you had IR based cameras placed around to assist.

[@Dashtin21]

Detection system's ideal position would be like right above so your sticking out your hand with the gun(assuming your pointing your gun) that would have been detected since the background/environment is not black.

[@dantedamean]

I have to imagine that detection would need to be more body language based. If you could tie the system into the 911 system, then when a city gets a 911 call about a robbery this could filter the footage in an area to find the potential suspect and track his location based on other cameras.

[@MichaelScholten]

A visual system like this will certainly have it's limitations. A system like Destin mentioned that uses another form of detection, like microwave/radar, that can see through objects such as clothes, and determine the difference between metal and skin/cloth would most likely be more accurate, however, then you're dealing with invasion of privacy along with various forms of radiation. Obviously this doesn't mean that only one type of sensor would be used world wide. Just as a business can opt to use "dumb" motion detectors over a more sophisticated camera system due to cost likewise it could be decided to just use camera assisted detection (like in Destin's video) in one location while another may opt to use a more robust system that will certainly have a higher cost, both financially and socially.

[@TheKuzmovka]

Destin, this was very well executed, and I like where your head is at. I am currently a Political Science student at a large public university in Colorado. I have some concerns about what this technology might hold in store for the average citizen. Here in Colorado we have campus carry and my primary concern is that in the event of an active shooter this could manifest in a situation where someone defending themselves gets shot because this technology identifies them as a threat. How can something like that be addressed? You mention in the video that there is a potential for this to happen and I think that is something which needs to be considered more heavily. Secondly I would like to consider further the implications to privacy. It is well documented that in the UK there are literally hundreds of thousands of CCTV cameras peppering London. I see a potential for this technology to encourage that sort of Surveillance State in the name of "public safety." Again, you mentioned in your video your concern for the 4th Amendment, and I would like to take a moment to reflect on how the propagation of this technology could very easily spin out of control. What are the limits? At what point does this technology go too far, and what are some practical limits to it? Given that Americans have already consented to millimeter wave detection in things like airports, could a system like this potentially desensitize a populace to further incursions on their rights? I would like to conclude by thanking anyone who read that novel and actually considered it. I understand that the spirit of this technology is to help the public and aid in offering some sort of solution to what is perceived to be a large problem in this country. I'm not taking a stance one way or another, I am just concerned about abuses and how those sorts of things may play out for the average person.

[@Systox25]

TheKuzmovka this software looks really simple and stupid Imagine you take the software from self driving cars and train it on this! It would be able to recognise not only a gun but also other weapons like a knife, actions, persons, gunshots,... and yes, this kind of Technology what we see in this video is so simple look what Michael Reefs did with that: Drones that fly in your head Lasers that aim at your eyes I think Destins lies to him self with this project it would help! He perfectly knows this is not a fix for that problem but a dirty workaround!

[@mrsuperguy2073]

To your first concern, I would imagine that any images of someone in an active shooter situation with someone identified as brandishing a gun would have to go through a person who by looking at the footage should be able to determine if the person is a threat or not. Actually, I'd go as far as to say that innocent civilians defending themselves and other people with their own weapons are less at risk of being misidentified as threats with this AI system because someone off site who is not at risk of getting shot if they misidentify an actual threat can take more time to make the determination than someone in the heat of the moment.

[@marshallhorton1216]

In your studies have you found many instances where a CC'er was able to assist in an active shooter situation? My greatest fear with the whole CC logic is that you would somehow be able to help in an emergency situation like an active shooter and not be a hindrance to actual emergency services or worse, be a target yourself.

[@SCrcSd]

Marshall Horton check out cctv in uk on you tube cc’ers assist with knives and alll objects

[@JeremyStreich]

@@mrsuperguy2073 In that instance though, it isn't misidentifying. It identified someone holding a gun and notified people with that information. Which means if a innocent civilian is caught on camera holding a gun for self defense (but the perpetrator is out of frame), the police would still get contacted and come to check out the situation. Te police would want to talk to the innocent civilian, and get as much information as they can. I see that as a win in the system. If the police mess up, and shoot the civilian for being armed, that isn't the system's fault -- that is bad police work.

[@ninehundreddollarluxuryyac5958]

That machine learning program looks really useful. It looks like he bought the program and all his time was spent training it. Could you do a video which briefly explains how the program works, then tell us how to set it up and train it to recognize different things? Maybe a follow-up video could show how to have the computer give an output like closing a switch or numerical x-y in frame positions so it could be used to automate stuff like a sweeper arm that removes flawed product from a conveyor or an x-y-z gantry to pick a part out of a bin.

Hope it makes you feel better but I did infact see this in my recommend. Good job KZbin.

[@DrunkGamerShow]

My first "gut" thought is that while I see the advantage of a system like this plugged into a security system, this feels too reactive. While I appreciate any and all attempts to help decrease response time and increase the accuracy of information, the solution we need now is the one that stops the shooting from starting. All that said, what y'all have done here is amazing and I applaud the effort and ingenuity required to create this product. Its truly amazing.

[@ericruhlmann6817]

I know exactly what you mean. I had the same thought. Maybe in places where guns are absolutely not allowed, such as schools, it could be tied into an alarm system that sounds as soon as it detects a drawn gun with a high(ish) degree of certainty. If it could catch it quick enough, it might deter all but the most dedicated would-be attackers. There are still a lot of issues that would arise with that, like finding a way to prevent the police from rolling out for every false alarm, but even then I think everyone would agree that a false alarm/preventing an actual attack would be infinitely better than one that is carried out. It'll be really interesting to see how this technology develops and is implemented in the future.
