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 demoNcutImage to see a demo
or...
type main to initialize the paths to subfolders
3) You can now try any of the functions
The files were tested under matlab 6.5
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: segmentation given similarity matrix W
[NcutDiscrete,NcutEigenvectors,NcutEigenvalues] = ncutW(W,nbSegments);
