i have colored images of same thing taken in series one after another with a very small time interval. Most of the region in the image is white except the small colored spots. i need to identify the colored spots using matlab. Professor told me first convert the colored images to grey images, and then convert grey image to binary image(i.e. points above certain intensity as 1 and rest as 0).Conversion to binary has been done with 'mask' command. Then he says, in next step use some algorithm to cluster the spots in each binary image(i.e. cluster the 1s). similarly do for all images,analyze them and conclude where is defect(spots). i have uploaded one colred image as a sample, and its greyimage and binary image.

Why is this a different question than before? http://www.mathworks.com/matlabcentral/answers/158803-finding-the-coordinates-of-points-with-maximum-intensity It's the same image and you're trying to find the spots like before. And you got some good answers there. Why are you asking again? I think you misunderstood your professor. The next step is not to "cluster the spots" but to label them, then call regionprops - I gave you a link to a demo. Did you try it? I mean, that's about all I can do since, even though it's a trivial problem, I assume you don't want me to just do it outright for you.
