I'd like to take a grayscale image that contains white blotchy areas and identify the center of these areas. For example, if there's an area that contains pixel values above 240, I want to be able to get the x,y position of the middle of that area. These images explain pretty much what I'm trying to accomplish:

As you can see, I'd like to figure out the center of these areas so I can mark them. Keep in mind that the areas may be irregularly shaped. Also, there would need to be some way of separating the white blobs so they can be considered separate objects. Maybe they are considered separate only if there's a certain amount of black pixels between them or something.
