Use the convex hull, bwconvhull(). Subtract the original image from the convex hull and call bwlabel
indentsBinaryImage = bwconvhull(binaryImage) - binaryImage;
[labeledImage, numberOfIndents] = bwlabel(indentsBinaryImage);

Amith Kamath on 9 Jan 2013 and the convex hull concept would help. I suppose you need to isolate each blob using and then find it's convex hull, and then the number of black blobs inside the convex hull will give you the number of folds. Hope this helps!
