Dear Researchers,
How can I we measure how many indentation or foldings are present in the three objects presented below

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

http://blogs.mathworks.com/steve/2011/10/04/binary-image-convex-hull-algorithm-notes/ and the convex hull concept would help. I suppose you need to isolate each blob using http://www.mathworks.com/help/images/ref/bwconncomp.html 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!
