See my image segmentation tutorial, "BlobsDemo" http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

In short, you process your image until you get to an image that you can threshold into foreground and background. Then you call regionprops on the foreground and ask for the 'Orientation' of all the blobs. That's the angles of the major axis of an ellipse fit to the blobs.
