colormap(hot)

?

[Adam]

I = imread('cameraman.tif');

subplot(121), imshow(I,hot)

subplot(122), imshow(I,copper)

don´t work

The whole figure retains the colormap, not just the axes. Thus both subplots retain the newest colormap. It sounds like you're looking for something like this:

Specifically, that two different images of themselves and put both the seat and I saw the difference.

subplot(131);

I = imread('board.tif');

J = rgb2gray(I);

imshow(I)

subplot(132);

imshow(J);

XFUSmean1 = wfusimg(J,I,'db2',5,'mean','mean');

imshow(133);

imshow(XFUSmean1);

but this is for RGB and lends it does not work

Adam, did you try freezecolors?
