Counting objects that leave the frame. #275

Open cpena107 opened 7 years ago

cpena107 commented 7 years ago

I am trying to count the number of objects coming in and out of the frame, but I notice that the prediction boxes are arranged in a list going from left to right and top to bottom of the frame. How can I single out each prediction box as a separate entity?

I also notice that the memory allocation of each, no matter if a new item was added to the list, it changes every iteration.

@astaroth106 To be clear, are you talking about generating predictions for a video (camera or saved video file) - or for an image?

cpena107 commented 7 years ago

@abagshaw Yes it is for a video (either save it or not does not matter)

I've tried doing some object tracking myself and it's quite difficult because sometimes the prediction is lost in frames and isn't maintained throughout the object's presence. I am going to try and do more object tracking work which will partly solve your problem but I don't think it will work or that i'll be able to share it. Good luck!
