./build_graphCutMex.m - function to build the wrapper
./graphCutMex.m - the description of the implemented function
./example_graphCutMex.m - the example of usage
./maxflow-v3.03.src - C++ code by Vladimir Kolmogorov (the code was slightly modified) http://pub.ist.ac.at/~vnk/software/maxflow-v3.03.src.zip
./graphCutMex.mexw64 - Win x64 binary file for the MEX-function compiled using MATLAB R2014a + MSVC 2012
./graphCutMex.mexa64 - Linux x64 binary file for the MEX-function compiled using MATLAB R2012a + gcc-4.4
USING THE CODE
-
Install MATLAB and one of the supported compilers
-
Run build_graphCutMex.m
-
Run example_graphCutMex.m to check if the code works
The code was tested under
- Win7-x64 using MATLAB R2014a and MSVC 2012;
- ubuntu-12.04-x64 using MATLAB R2012a and gcc-4.4
OTHER PACKAGES
- BK max-flow/min-cut algorithm with interface supporting dynamic graph cuts: https://github.com/aosokin/graphCutDynamicMex_BoykovKolmogorov
If you need to solve many similar graph cut problems in a row consider using dynamic graph cuts.
- IBFS max-flow/min-cut algorithm: https://github.com/aosokin/graphCutMex_IBFS
The IBFS algorithm has polynomial time runtime guarantees. The BK does not. In my experience BK works faster for graphs built for standard 4(8)-connected grid MRFs. If the graph becomes more complicated (especially hierarchical) consider trying IBFS instead.
- QPBO algorithm https://github.com/aosokin/qpboMex
If you need to minimize energy with just a few non-submodular edges try using the QPBO algorithm
