I'm a relative newbie when it comes to image processing, so please bear with me...
What I want to do is to set up a static camera such that it can track the motion of a person wearing a particular color marker walking around in an interior room (no windows). The "color marker" can be something like a t-shirt with a unique color distinctly different from the background, and I think I'll need to take periodic snap-shots of the room to simulate real-time tracking as closely as possible. In effect, it's a simplified scenario for person tracking.
For now, I'm just trying to get the color detection part of my project working. I think I should be to just do a simple background subtraction between a snapshot by the camera and a reference image of the background, and that should be able to give me good color detection. The issues I'm concerned with:
a) Do I need to worry about different hues/illuminations of the same color?
b) Is this a realistic method to implement with the PIL, or would I have to deal with issues of speed while trying to track the marker?
