Shadow Detection_Shadow Elimination

Dear all

I am estimating the background with LMS(adaptive filters) in a video surveillances, so I have to detect all the motions. The big problem is shadow, I have to Eliminate the shadow, I mean it should detect as a background, but because of motion,it is a part of moving object.

What is your solution about this problem,I mean about the "Detection of shadow of moving object". Start a New Thread

can we use the pixel intensity, because the shadow can be considered as a region with the same intensity level. Just my idea

If you are working in an RGB colour space, you might want to convert to HSL.
The Hue does not change in the shaded areas, but the luminance will change
(i.e., the colour doesn't change, but the amount of light reflecting off the
surface will change in the shadow).
