Did you try anything already? The more you show from your own effort, the higher is the motivation of the readers in this forum.

yes i did try simply giving threshold for x and y cords. for the image above there was certain rows and cols of 0's and rest with values i tried separating 0's with 'if' functions but its not working.it just gives x & y values in command window.

Not sure what you're looking for. It looks like you've already found the green and are displaying it separately.

See my File Exchange for color segmentation demos: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
