I'm doing vehicles tracking project. The video is a one-way, no vehicles occlusion. After doing background subtraction, erosion and dilation, I get bounding box objects for each frame, and I can find $centroid(c_x,c_y)$ from that. So, the next thing I want to do is blobs tracking. Here is what I'm thinking on how to do the blobs tracking:
- At first frame, store all (cx,cy,id)
- Next frame, calculate distance each new (cx,cy) with each of old (cx,cy)
distance < threshold, update the old (cx,cy) which qualify the formula
distance > threshold, check if the cx,cy is
near the entry coordinate(e.g. around x,y=0-640,0-40), if
yesstore new (cx,cy).
Is it right and possible to apply to tracking?
