Vibhu, you can edit your original question rather than make a new one with the same topic. Also, please show us what you've done so far. Or show an image you want to segment. Or read this post (http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer)

If Sven is right about you wanting to find hands/skin, hsv color space would be best for segmenting skin gamut. LAB or RGB color space would be no good. Even with HSV you can't simply go on hue, though that's the major component. You have to put in some curves to make the gamut "bow out" in the middle and come back in at the top and bottom so that you get the boomerang-shaped gamut characteristic of skin.
