So some kind of filtering like based on size or shape. See my Image Segmentation Tutorial for a demo on how to use filtering on detected regions. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

You can use morphological operations for that. imopen will remove smaller blobs. imclose will fill in small gaps. If there are still noisy blobs left after that, you can use regionprops to determine the area of all the objects, and exclude the ones that are too big or too small.
