Suppose your image size is 50*50, then u separate each RGB plane.

image=imread('img.jpg');

R=image(:,:,1); or R=image(1:50,1:50,1);

G=image(:,:,2); or G=image(1:50,1:50,2);

B=image(:,:,3); or B=image(1:50,1:50,3);

by varying row and column of each plane you can check pixel values.

I hope this is answer for your question.

在 MATLAB Online 中打开

I=imread('board.tif');

[m n k]=size(I);

for l=1:k

    for i=1:m
        for j=1:n
           if  I(i:j:l)==1
               do
           else
               dont
           end
        end 
    end
end
