See my Image Segmentation Tutorial: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
My function that extracts the N biggest or smallest blobs is included in the demo I attached below. Once you have the 4 largest regions you can then call regionprops to measure things in them like the area, perimeter, equivalent circular diameter, etc.

Steve Eddins has a demo for the k-means method for color segmentation: http://www.mathworks.com/products/demos/image/color_seg_k/ipexhistology.html
