Graph Partitioning Active Contours (GPAC)
DOWNLOAD
Matlab code and compiled dlls
Source code for the mex files
USAGE
Binary
For the Matlab code with binary dlls, simply unzip the files in a local directory and run 'tryGPAC' from the Matlab console. To test the algorithm with different images, you can change the name of the image in the first line of 'tryGPAC.m'. We strongly recommend to use fairly small (or resized) images, otherwise the similrity matrix computation and the curve evolution will be extremely slow.
Source
To compile the C++ mex files you can call the two scripts I wrote: Compile_GPAC and Compile_SimByTiles. If it is the first time you use mex inside Matlab, you will need to call mex -setup to allow Matlab to locate the C++ compilers in your system.
