A new convexity measure based on a probabilistic interpretation of images. Rahtu E, S., M., &., H., J. IEEE Transactions on Pattern Analysis and Machine Intelligence, 28(9):1501-1512, 2006. abstract bibtex In this article we present a novel convexity measure for object shape analysis. The
proposed method is based on the idea of generating pairs of points from a set, and
measuring the probability that a point dividing the corresponding line segments belongs
to the same set. The measure is directly applicable to image functions representing
shapes, and also to gray-scale images which approximate image binarizations. The
approach introduced gives rise to a variety of convexity measures, which makes it
possible to obtain more information about the object shape. The proposed measure
turns out to be easy to implement using the Fast Fourier Transform and we will
consider this in detail. Finally, we illustrate the behavior of our measure in different
situations and compare it to other similar ones.
