Hi every one,
I'm working on image steganography and it works very well but later i noticed when i first read image (512x512x8) even before doing anything concerning image hiding the displayed image look like attached one,
bw = double (imread('barbara512.bmp'));
imshow(bw,[])
any ideas why?
thanks in advance.

Do not use double(imread()) for this purpose. Use im2double(imread()) . And try imshow() without the []
The variable you are using hints you are expecting black and white, but it looks to me as if you probably are using grayscale.
