dispimg.m

kmeans clustering in matlab

function dispimg(img)
% displays an intensity image (on any intensity scale) using a gray-scale colormap
% with 256 colors. The intensity data are scaled to use the full colormap, i.e.,
% the darkest pixel is mapped to 1 and the brightest to 256

% first create a temporary image which maps the darkest pixel to
% 1 and the brightest pixel to 256, using the utility function scale.m
y = scale(img,-Inf,Inf,1,256);

% now plot the image.....
figure;   
image(y);
colormap(gray(256));
