+% function RGB=showmask(V,M,hue);

+% Input:

+%    V = image

+%    M = nonnegative mask

+%    hue = a number in [0,1], red,yellow,green,cyan,...,red

+%          a char, 'r','g','b','y','c','m'

+%          or a matrix of the same size of image

+%          eg. hue = mask1 * 0.7 + mask2 * 1;

+%   

+% Output:

+%    RGB = an RGB image with V as shades and M as saturated hues

+%    If no output is required, this image is displayed.
