Just use rgb2hsv(). You should be able to get what you want by using that. Otherwise, just use the formulas.

no sir, i was searching for rgb to HSI color space, and if i am true, i've learned that both are not same. only similarity with the hue value. is it right

Like I said, you can just use the formulas. Why do you think that the difference will be important? http://en.wikipedia.org/wiki/HSL_and_HSV Let me see your image. Chances are that you can get what you want with HSV. If you can't, then show me your image and explain why it can't give you what you need.
