[@tobieabel7474]

Another great video Piotr! I am currently working on a project using Supervision to track the speed of hand movements as part of a hand gesture recognition system, and your tutorials are really timely. I'm detecting the hands, performing some minor perspective transformation as you do here, tracking their movements within certain zones, and calculating their speed over several frames to determine the specific gesture. One issue I'm noticing is that Byte track has a tendency to lose detections even within a small area, and I was wondering if you have any tips for improving tracking performance other than playing with the byte track parameters?

[@Roboflow]

ByteTrack is using IoU to match boxes between frames. So if your hand is moving fast you can loose tracking.

[@elhadjikarawthiam4595]

Great job as usualy @Piotr. Is there a way to automate the generation of points A,B,C,D because I believe the current implementation requires one to use a mouse to hover around the the 4 points to get their cordinates, that won't be feasible in production.

[@Roboflow]

There is no way to reliably automate this. But you only need to do it once for each camera. So you can save the configuration in JSON and load it.

[@ObsidianMusic842004]

Greetings. First of all this is an excellent video, and I learned a lot from it. I just have one question, I'm confused regarding what deque is and why did we use it in our defaultdict?

[@JellosKanellos]

Thanks a lot for the awesome video Piotr! One thing I always wonder about applying yolov8 object detection to video is: it seems kind of naive to handle every successive frame as a separate image. What I mean by that is, can't we be more smart about taking information from the previous frame(s) into the inference of the current frame? For example: if there was a car detected somewhere in the camera image, it must be somewhere near that position in the next. What are your thoughts about that?

[@Roboflow]

Hi! Depends what you do. There are some systems. Like parking occupancy, where you can easily get away with running inference every 1 second or even less frequently, and just assume all cars are parked in the same places. Here the cars are moving, and that movement is particularly interesting for us. We are using ByteTrack. This tracker use only box position and overlap to match objects. If you will not run inference sufficiently often, there will be no overlap between the frames, and you loose track.

[@pingyang8963]

Awesome presentation! Thanks for sharing. One question, since speed is detected, Is there a way to get the distance to the camera instead of speed?

[@Roboflow]

Well we ould need to know the distance from camera to some reference point.

[@pingyang8963]

@@Roboflow for the reference point, Will that possible using 2 cameras (which has a known distance between those two cameras) and creating a fused map from the two cameras and get the distance and speed?

[@mayurmali2715]

gys any ideas on what new features we can add to this?

[@jeffcampsall5435]

There needs to be correction factor along the path…it’s like drawing the globe on a flat piece of paper. If you watch cars driving away on the right side, their speed is 140 kph and “reduces” to 133 kph: which is very unlikely. I know the trapezoid can be limited to those vehicles closest to the camera but I thought you might like to tweak your algorithm. 👍

[@Roboflow]

Sure 👍🏻 the whole algo is a bit of simplification as we only have 4 points. If road is not perfectly flat and straight some divisions may occur. Still I think it’s one of the complexity/accuracy tradeoff is okey.

License plate OCR is on my TODO list. As for fine tuning. If you start from COCO dataset and that’s fine tune it on dataset with custom classes it will detect custom classes. If you wan to preserve that previous knowledge you would need to train model on dataset that is a combination of your classes and COCO classes.

I am new to this, however, I am thinking of trailing the public, then purchasing the starter subscription to start a side project. For this specific project, how much would it cost to keep it running for 24 hours a day? Also, can you provide me with an estimate cost if this were to be scaled up to 1000 cameras? I am only looking for an idea on the cost to run such a programme on your typical camera over a motorway (like the one in this example). I am assuming it would go through roboflow, but I could be wrong. I am looking for the easiest option. Many thanks.

[@Roboflow]

Easy is a bit relative depending on your skillset and hardware. Here are a few ways to think about it: You can deploy with the hosted API. This requires devices with internet connection. You'd then be able to choose at what rate you hit the API for predictions and that would impact pricing. 24/7 with 1 prediction per second is 86,400 API calls per day or ~32 million per year for each location. 1,000 cameras means ~32 billion per year. You could reduce the rate of predictions to bring down API calls but then you won't have a real-time system if that is what you need. Alternatively, you can deploy your models onto the edge devices using Roboflow Inference and do the same operation but use your own compute. In either scenario, this level of usage requires a conversation with our Sales team to offer you Enterprise pricing roboflow.com/sales
