A really great tutorial. I have one question though, while running script.py on your video it works fine, but when I run it on my video at 12% it quits with error " in _get_ufunc_and_otypes raise ValueError('cannot call `vectorize` on size 0 inputs ' ValueError: cannot call `vectorize` on size 0 inputs unless `otypes` is set". Any ideas why?(I added otypes=[object] as second vectorize parameter and I am waiting for 12 hours now.) And how could I display class name alongside tracker id and group the tracking count displayed on zones according to vehicle class?
can you make videos on this topic Traffic flow tracking at an intersection based on direction-to-direction analysis involves detecting vehicles and determining their movement direction within predefined regions
From which direction and how many vehicles have gone on signalized intersection with their class name ?" cannot be showed .. how can we place a name in the line and for example D is the one direction A is the another direction how can we show how manh vehicle can pass from d-A
@Roboflow, all: Has anyone managed to run YOLOv8 on a Coral Edge TPU? I've converted the YOLOv8 model: model = YOLO('yolov8n.pt') model.export(format='edgetpu',int8=True) I get: Model successfully compiled but not all operations are supported by the Edge TPU. A percentage of the model will instead run on the CPU, which is slower. Number of operations that will run on Edge TPU: 230 Number of operations that will run on CPU: 26 Running the model with the "yolov8n_full_integer_quant_edgetpu.tflite" file (and a properly plugged in and recognized Coral Edge TPU USB) results in detection times at least two times slower compared to running on my CPU. - Are these the correct steps? - Is this an inherent problem of the YOLOv8 model? i.e. not all of it can be efficiently quantized to run on a Coral Edge TPU? - What hardware do you guys use for edge real time YOLO?
Can you please upload a tutorial on using YOLO-NAS and BYTETrack for object detection and tracking on custom dataset? (if possible, pls include the annotation part for videos of the dataset as well)
I personally prefer this format of video where you work from the IDE rather than Colab as I find it easier to follow the structure of your thinking, how you go about solving the problem piece by piece.
Impressive job! I have one question, although this video was captured by a drone, the camera lens remains stationary. In most cases, the drone is moving, so fixed-position bounding box is not applicable. Is there a way to address this issue? Thank you!
I am working on a project, for detecting saplings in a field. but when the drone is taking a turn to change the lap (basically moving into other lanes) the previous lanes are also coming like 1,2 of them and saplings in those laps are counted again. Is there any solutions for this?
Did you tried any image stitching? So I’m short instead of prow easing video. Pick frames every 1 or 2 seconds. Stich them together to form large image. And process that large image?
@@Roboflow actually I have a video from client, I have yolov8 model to detect saplings and the video is shot from drone like if the drone move in first lap, it covers first 4 lanes and when takes a right U turn and move to the 2nd lap the video has previous last 2 or 1 lanes, and saplings on those lanes are counted again, will image stitching work?

Great video, really helpful. I am building a people tracker to count how many people are in various zones of a premises and where they have walked from so this is a really useful piece of work - many thanks
I have lost hope in finding the answer of my question @roboflow team. I have been commenting on your last 3-4 videos for one help. I want you to help me with Autodistill auto annotations video,where I want to check the annotated images manually so that i can correct the annotation which is wrong and missing. You told me that you will upload a blog, if its already uploaded please share the link or please make a tutorial on the steps . Thank you .Please i need your help

I got a error while compilation with visual code where it state that objects are nun cannot iterate the null objects plz suggest how to solve that issue
thank for great tutorial. I want to implement a tracker which counts and track fruits on tree. The problem is some of the fruits are counted more than once. does anybody have any ideas? is there a way to keep the tracklets in ByteTrack for longer duration?
Video from you really helps me a lot I appreciate it . I have a query How can I count number of objects entered and pass from polygon and show the count on polygon
Hey dude, it's going to sound a bit lame, but my training has failed many times already and I think it's because of my dataset, I need it to be able to detect cars in that same kind of camera angle, so... can you give that database or tell the link where you got it from please 😅
Thank you for a great work! Would be happy to see you continue experimenting more😊 Question though, I assume Polygon instance only contains information whether the ID is in the zone or outside without actually showing whether it crosses the line to exit? The reason I’m asking this is that my projects has a lot of occlusion, so it’s quite often for model to lose track. What will happen if object is not tracked anymore, but it never did actually cross the line to exit? Thank you very much!
So what you are looking for is information that given ID was outside and at some point it cross and is inside? To prevent ID popping out of nowhere in the middle of the zone and get counted in?
Not exactly. I want be sure that actual zone exit (crossing the line) won’t be confused with model losing the object. Say the object disappeared (due to occlusion) inside the zone. Would the polygon logic treat it as zone exit?
@@Roboflow I'm eager to use and promote your framework. please let me know if you can provide this information: I want to be sure that actual zone exit (crossing the line) won’t be confused with model losing the object.

Thank you so much for this video, it is a lot fun learning from your videos! I have one question, how do I convert the results I have gotten into a output video? I have tried, however I have only gotten the video without any labels or bounding boxes.
oh I GOT IT! Thank you nonetheless for making these awesome videos! Is it possible for you to create a video whereby ReId is combined with tracking algorithm(eg ByteTrack or BOTsort)? Thank you once again!
Really great project! I would like to save the tracking data for further analysis - speed calculation, trajectory conflict points. What would be the best way to do it? Let's say the result should be a dictionary with all tracked IDs as keys and the values will be a list with the object coordinates in each frame: {id1: [[x1,y1,frame1],[x2,y2,frame2].......} Thank you!
I trained our network with custom dataset. with YOLOv8 The training period lasted a long time. I want to test the performance of my test set with the network I trained at another time. Is there any other solution than retraining the network?

impressive! Actually it would be nice to draw the zones (bounding box) using mouse dynamically and assign a color, how can that be done? any specific libraries for it?
For "solar panel counting using SAM" ...which process is better >>> 1. detection followed by segmentarion Or 2. segmentation followed by classification
We can do many different things. You can label with single or multiple categories. You can assign tags. You can cluster images based on similarity. Could you be a bit more specific. What solution are you looking for?
@@Roboflow thank you! reverse image matching to find the closest match from an image set using the entire image instead of labeling things inside the image... let me know!

i personally enjoyed the IDE more than Colab and please do the ones you talked about. traffic density, vehicle speed even the gap between vehicles travelling in the same direction. This will be interesting. What if the zones can be entered from the UI instead of hard coding them. just a thought!
