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).

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

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".

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".
