Please cite the following if you plan to use the code in your own work:

Tested on matlab R2009b.
Installation Notes :
1) After you unzipped the files to mydir,
put the Current Directory in Matlab to mydir
2) In the matlab command prompt,
type compileDir_simple to compile the mex files (ignore the error on the C++ non-mex file; needs to be done once)
3) You can now try any of the functions
type demoNcutImage to see a demo of image segmentation
type demoNcutClustering to see a demo of point cloud clustering
Other top level functions:
NcutImage.m: given image "I", segment it into "nbSegments" segments
[SegLabel,NcutDiscrete,NcutEigenvectors,NcutEigenvalues,W]= NcutImage(I,nbSegments);
ICgraph.m: compute Intervening Contour based pixel similarity matrix W
W = ICgraph(I);
ncutW.m: Given a similarity graph "W", computes Ncut clustering on the graph into "nbSegments" groups;
[NcutDiscrete,NcutEigenvectors,NcutEigenvalues] = ncutW(W,nbSegments);
Release notes:
2010, January 22: release of all c++ source mex files compatible with matlab R2009b
2006, May 04: release version 8: fixed incompatibility issues with new matlab
2004, June 18: release version 7: initial release
