How to find Region of interest using image segmentation

[Umesh17_89]

I am doing image segmentation using region growing algorithm.
I have created Region and Pixel class where each region has list of pixels.

public class Region {
    private List<Pixel> pixelList;
}

Pixel class has fields like r,g,b, hue,saturation, brightness of individual pixel in image.
The result of segmentation is list of regions.

List<Region> segment(){..}

I want to find one region object or sublist of region objects which is "Region of interest".
Please advice me about finding this. Is there any algorithm for this? Please help.

Image processing is a VERY specialized field. Read some of the literature on the subject, including papers from from the SIGGRAPH group of the ACM. I don't doubt there are people who lurk on these forums who are knowlegable in the field, but there can't be many... :-)

Thank you for suggestion :) I will read some literature on this.
