It would be helpful if you could post an image, there are different types ways to segment an image. One would be to use Canny and get the binary image

See my image segmentation tutorial where I find centroids: http://www.mathworks.com/matlabcentral/fileexchange/25157-image-segmentation-tutorial-blobsdemo. From there it's easy to use the Pythagorean theorem to find the distance between all the centroids.
