Yes, also I am hopping on board the train called motion tracking.

I've been fooling around with them cv.jit objects for a little while now but don't really know how to solve this problem:

I want to write a patch which registers moving objects of any color (people filmed from above) against any background. So I calculate the difference between consecutive frames.

Great, so now I've got moving people walking around as trackable blobs. But there are 2 problems:

The computer forgets about them as soon as they stop moving (they "dissapear" because the computer only sees movement): I want the computer to remember them until they start moving again.

Also, I'd like to improve the way that cv.jit.blobs.sort works: I want it to not only see how close the blobs from this frame are to the blobs from the previous one. I want it to see how close the blobs from this frame are to the EXPECTED positions of the blobs from the previous frame (taking into account their speed and direction).

I'm hoping some of you will be kind enough to give me some good pointers 'cause I'm now trying to make my own cv.jit.blobs.sort and blob-remembering algorithm in Java and quite frankly it sucks *$#@!, big time.

More motion tracking!!
