I remembered seeing a similar post before but cannot find it in the archives. I know cv.jit is a good choice to start. But which objects in cv.jit are better for this situation ? Any suggestions ?

Thanks.

If you go to the object guide, you can search by group.
The objects are: [cv.jit.framesub]; [cv.jit.HSflow]; [cv.jit.LKflow]. [cv.jit.track] is also a good one.

Hope this helps.

Keeping the numbering consistent is a definite problem that has yet to be resolved. That said, the cv.jit library is excellent, and the numbering issues are to be expected once you dig in and see how they work…they index from the left top and scan to the right, so when blobs cross over each other’s X axis, they switch. Hopefully some clever workaround will surface, and likely there are some I don’t know about.
