kmeans clustering in matlab

% simple script to illustrate clustering of face images

load dstraight;


cimages = crop_images(dstraight,30,100,30,90);  % create cropped images
dispset(cimages);

% cluster the first 4 images. Note how the 4 individuals are
% largely separated into 4 different clusters.
clusterimages(cimages(1:4,:),4,1234);

% effect of different seeds (get different answers)
clusterimages(cimages(10:13,:),4,1234);
clusterimages(cimages(10:13,:),4,5678);
clusterimages(cimages(10:13,:),4,910);
