说明： 经典的图切算法NormalizedCuts.将图论应用到图像分割上，可以限定分割块数，有效分割图像。运行：demoNcutImage.m，即可看到效果。读取的图像名称和块数，可在程序中修改。
(classic NormalizedCuts MAP algorithm. On the map will be applied to image segmentation, Segmentation can block limited number of effective segmentation image. Operation : demoNcutImage.m can see results. Read the name and image of a few blocks, the procedure can be modified.)

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);
