Fast Field Algorithm

A simple and fast algorithm for generating doubly-stochasstic matrices.(matrices, where the sum of each column and each row is exactly 1).Each matrix is chosen uniformly from the space of all NxN doubly-stochassticmatrices.Note: the generated matrices are indeed doubly-stochastic, but it's...

This software implement the fast continuous max-flow algorithm to 2D/3D image segmentation. It provides three implementation in matlab, C and GPU (cuda based). It provides the source files. So it is easy for you to incorporate the algorithms in your applications.Image segmentation can be modeled...

This software implements the fast continuous max-flow algorithm to 2D/3D multi-region image segmentation (Potts model). It provides three implementations: matlab, C and GPU (cuda based). All the source files are provided. So it is easy for you to incorporate the algorithms in your own...

This is an extremely fast implementation of the famous Hungarian algorithm (aslo known as Munkres' algorithm). The new version (V2.2)is about 1.5 times faster than the old version (V2.1). It can solve a 1000 x 1000 problem in about 20 seconds in a Core Duo (T2500 @ 2.00GHz) XP laptop with Matlab...

Even if totally m-coded, this routine is particularly fast in computing convex hull of 2D points. In many cases seems to be much faster than the matlab library routine. The main reason is that, differently from convhull, this algorithm jumps the call to unique function which can be very slow for...
