I just started to learn image processing. My question is about RGB image. I understood that RGB values should go between 0 to 1 in 3 dimential matrix, but I see all kind of value but not 0...1 Here is my code:
Image=imread('someColorImage.jpg');
s=size(Image);
for i=1:s(1)
for j=1:s(2)
% handle rgb negative
disp(Image(i,j,1));
disp(Image(i,j,2));
disp(Image(i,j,3));
end;
end;
What is wrong?

For 8bit representation, RGB values go from 0 to 255. The 1-3 index is for Red, Green, and Blue, respectively.
