What format are they in now? Normally most RGB images are in 8 bits per channel (24 bits total) unsigned 8 bit ("uint8"). What are yours? I'm not sure what you want to convert into what. What are you starting with (a 3D RGB image, or 3 separate gray scale color channels), and what do you want to end up with (a 3D RGB image, or 3 separate gray scale color channels)?

HERE IS MY CODE clear all; close all; clc; warning('off', 'Images:initSize:adjustingMag') RGB=imread('Untitled.png'); figure(); imshow(RGB); %-------- R=RGB(:,:,1); G=RGB(:,:,2); B=RGB(:,:,3);
disp('r componet'); R=RGB
disp('G componet'); G=RGB
disp('B componet'); B=RGB
R(:,:,2)=0; R(:,:,3)=0;
B(:,:,1)=0; B(:,:,2)=0;
G(:,:,1)=0; G(:,:,3)=0;
figure(2); imshow®; figure(3); imshow(G); figure(4); imshow(B);
