在 MATLAB Online 中打开

cmap = copper(22);     %some color map
outimg = ind2rgb( uint8(locatn), cmap);
image(outimg);

What do you mean by "pixels having the same value"? Do you mean, say, pixels having red color? And so you want to assign a green color to all pixels having "red" values? Meanwhile, why don't you look at my color segmentation demos in Image Analyst's awesome File Exchange?
