Did you run my Image Segmentation Tutorial? http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 All you have to do is replace Centroid by WeightedCentroid and it will give you the center of gravity. Centroid does not do that - it assumes all pixels in the blob are weighted the same (have the same gray level), in other words, it uses only the binary image, not the grayscale image.
