I was given 3 images, all are 2-dim arrays. One represents R (red), G (green), and B (blue). Each of these are of the same image but representing RGB. I am supposed to create a composite image using those three that are given. What is the best way to do this in Matlab? I read in each image, then I did this:
R = red; %changing variable name G = green;
B = blue;
I_rgb = cat(2,R,G,B);
I tried setting the dim = 3 but Matlab didn't like it because, I assume, the images are all 2-dim. The way I have it, instead of getting back one image, I get back the 3 images side by side.
