Vehicle Tracking, Labelling [closed]

Hi,

I am doing vehicle tracking, and my vehicles are detected using camshift algorithm. Now when I draw bounding box around each vehicle, I want to label them unique way to track and count each vehicle. Can any one suggest the criteria to label each vehicle with unique numbers. I tried labelling them but the lebels are shifting between first and next vehicle.

Any suggestions how to achieve this?

Thanks in advance.

Your question is very unclear. Are you aiming for automated or manual labeling?

Automated labeling. I store the bounding box Rect info in a vector but sometimes the same car has two bounding boxes and they are labelled with two labels.And sometimes when two cars come nearby the ROIs overlap and two connected blobs labelled with single label. So which mechanism can sort our this scenario at basic level. I am looking into non minimal suppression for clubbing multiple bounding box to single one, still working on it. But unable to get a general idea to label at a basic level.

I think you should look into trackers, and especially the split and merge issues related to that.

take a look at Hungarian algorithm + Kalman filter
