I have taken a photograph and got the ROI based on the color of the skin.Now i want to seperate the ROI from the rest of the portion.

What does that mean? You already have an ROI so I assume that is a binary image of which pixels are skin and which are not. What else more do you need? What are the two things you will have after you do this undefined "separation"?

Actually I want to get two separate images,one the roi and the other is the rest of the portion(meaning the remaining background,shoulders etc.
