Question

I’m able to do object tracking of different colors just by applying various thresholds. (for example.. http://www.youtube.com/watch?v=njab2bBps6U&feature=player_embedded)

However, I’ve been unable to determine a solution for tracking multiple objects of the same color.

I’m not looking for code to solve my problems, more just trying to figure out what the standard method isis and I’ll figure it out myself.

I’m using opencv with its python bindings.

This is not very hard. Here’s algorithm:

1. In the first (or some) frame find positions of all objects with the same color. It seems that you know how to do that.
2. Using Lucas–Kanade method and it’s implementation in OpenCV track all these objects in videostream (second and next frames).

Here’s example (video) of using it.

Here’s sample code (cpp, not python).
