Computer Vision: Crash Course Computer Science #35

[@danielkohwalter5481]

This is by far the greatest course that I had on my entire life about computers. I work with full flight simulators for pilot training and many things that I learnt here became so clear for me... We see many systems in a very superficial way due to those abstraction levels and with those classes I can see what's behind the scene, what's going on in a deeper way. Thank you, guys. Thank you very much for sharing all this knowledge and in a way so simple and easy to understand. You're the best!!! And I'm recommending the channel for everybody I know that likes computer science on any level of understanding!

This is probably the best explanation of computer vision I've ever seen in my life.

[@Firithfenion]

"not to ask for updates if you are frustrated" LOL this course is so informative and entertaining at the same time. Very good job!

[@Luke87o26]

I am currently studying Imaging Science at RIT and this is the best explanation I have ever found. One of the greatest refreshers of what’s going on sense I got here.

[@aaronfox3613]

Our university's robotics team is currently using OpenCV so our autonomous drone can see and navigate the world. Lots of theory, documentation reading, and pulled hairs come along with computer vision, that's for sure.

[@potterherry462]

Dude, I know what you feel I have been learning machine learning and most of the times it gets very frustrating.

[@GiveMeCoffee]

I really love this show, it's a great way to introduce concepts before having a full lecture at a college class, or to have a wide general idea of what the career path will include.

[@WistrelChianti]

Facinating to get to this one in 2023 in the context of where things have gone since.

[@tahsinl]

Great video! I'm taking a Computational Vision course right now. It was nice to know what you were talking about.

[@muhammadadeel1150]

Tahsin Loqman May I have your email address . I am interested in this course

[@Filwoj00]

The best online program, don't stop doin it!

[@IceMetalPunk]

For anyone who's interested, there's a (relatively) recent system called YOLO: You Only Look Once. Version 2 came out less than a year ago, if I remember right, and basically it uses computer vision techniques to classify many different objects in a scene in real-time video. As in, it's fast enough to fairly accurately detect and label many different objects in an arbitrary scene 24 times per second (24fps is a standard video frame rate). It's super interesting! :D

[@Huntracony]

Do you know if it uses the information it got from previous frames?

[@sophiacai8157]

Awesome naming for it!

[@BUDA20]

Only the current frame, also you use in general, downloaded pre-trained models for weights, so you can start detecting things easily, you can add if want new detection, but of course it takes a lot of work, real time HD video needs around the GPU power of the GTX 1080 Ti, depending on the complexity of the weights, but you can trans-code a video, with the labels added on them, and watch later the final results.

[@edmonda.9748]

@buda20, Thanks for referring to the type of gpu required for this, which answered one of questions as I'm building my own workstation for deep cnn, video object detection, ... Can you recommend minimum hardware specs? Seems to me a capable system has always been taken for granted. Thanks

[@knowledgemagnet4077]

Yes! 😁

[@user-oj3gb8nh2q]

I found the narrator very pleasant to listen to. Also the video was very good.

Great lesson. I can't wait 'til next week. Thanks!

[@ozzyfromspace]

You're an absolutely brilliant communicator! I'm doing a computer vision specialization on Coursera with the University of Buffalo and your high level intuition just gave me oodles of excitement. I dream of one day developing my own algorithm for real time navigation for data constrained systems. Thanks, really, this was a fabulous primer video, and certainly one I'll show my best friends. ☺️

YOU ARE AMAZING!

[@cesarbrown2074]

This could be were Quantum computers shine. It can analyze all that data all at once basically seeing the bigger picture.

[@Huntracony]

Self driving cars often (also) use LIDAR, which has the great advantage of knowing distances, so the car is able to see in 3d. The (biggest) exception to this is Tesla, which decided that normal cameras work just fine, to which I say sure, but why not make it even better?

[@sirtripalot2770]

Good quality LIDAR sensors needed for automotive applications are expensive. One of Tesla's goals was to ship all of their cars with the hardware needed for automated driving, long before their cars were capable of automated driving. Shipping the initial cars without this feature but with LIDAR might have been too expensive to be feasible. Using this approach, Tesla collected millions of miles of consumer data about typical driving conditions. This treasure trove of data enables them to understand under what conditions what sensors fare poorly and gives a large test set to compare algorithms on. I don't know if Tesla made the right decision. They might have problems getting their system working in urban areas or other challenging environments without the more detailed data that LIDAR provides, but the low cost of Telsa's sensor package enabled them to use consumers to collect data for Tesla, and that is a significant advantage for Tesla's engineering design team.

[@swatijain6898]

Mam very nice video, Mam please also made full course videos also with very easy explanation & cover only those maths which require for that course. Because your explanation is very simple

[@samuelgriffin1955]

[@daserstereichen]

At 5:52 you forgot to mention the bias value.

[@bobbobety]

Awesome video! How exactly are these image processing softwares implemented - would it be a low-level programming language like C, a high-level like Python or would it even be at the hardware level?

[@TalSoikis]

Shame no one answered before. Anyway, can be both. Python can be used in production and in testing (Really good libraries for complex computer vision like convolutional neural networks, object segmentation and so on). However when really high control over performance is needed, be it memory or computing speed, a low level language like c or c++ are used. Hope that helped :D

[@bobbobety]

Convolution just happened to pop out from nowhere. In case you are wondering, convolution is the operation that maps a set of values (also called N-tuple where N stands for the quantity of elements) to another set of values. Very simple example: _1,2,3,4_ is a 4-tuple _+1,+1,+2,+2_ is a simple convolution _2,3,5,6_ is a 4-tuple as result of applying the above convolution

A computing device should never change behavior depending on highly subjective factors, it should only do what it is explicitely told to do.

[@EclecticFruit]

If my computer can't lie then it's not really alive!

[@IceMetalPunk]

But then it's just a faster calculator :(

[@horsesrmylife78]

Even if something that is subjective is in the code, it’s still *in the code*, meaning that the computer is not making its own decisions. Only the programmer makes decisions based on subjective ideas.

[@nibblrrr7124]

The point is that the user's inputs to the program are no longer under the complete control of the user. Typing & clicking the same things might not get the same behavior/output, based on some ML classifier trying to interpret your mood/intentions/... more or less well. This *affective computing* approach is very different from regular UI design.

Could I still get into IT particularly cyber security even though I'm 24 and I don't have a STEM degree? and I'm a white male. Also would a A+certification help me? Please advise me.

[@bemusedalligator]

1: yes. 2: No one cares. 3: Yes

[@averagebloke4474]

Bradley Callaway no one cares because I'm a white male right? Because the push is for more women in tech if you don't know.

[@Pugpono]

At the end of the day, a business just cares about if you get the job done. Uncontrollable variables (i.e. gender and genetic skin cell melanin levels) are irrelevant in this scenario.

[@averagebloke4474]

XLpug yeah that's why most businesses including the government, and state have highering quotas right? Particularly for women right? None for men or especially white men. If you didn't know. That's goes directly against what you said I'd suggest to look into it if you don't believe.

[@koober_]

I can't speak for IT particularly but for CS (which is somewhat grouped with IT) it is definitely possible but much more difficult. At least with CS, you will have to show that you can learn a great deal from self-teaching, and be expected to perform just as well as someone who has completed a degree in an interview. I'm not sure how different it would be for IT, but I think it's definitely possible if you've been putting those extra years into extensively learning IT material. Ask around on career questions forums; I know there is one on Reddit for CS (r/cscareerquestions), so give it a shot if there isn't one dedicated to IT. I'm sure some people with experience in IT will be glad to give you some advice.
