How to hide watermark of an image via MATLAB?
-
Hi, I am new in MATLAB, I have been given a code which hides the watermark image into the bit0 of the original image: orig = imread('lennagray.bmp'); wm = imread('watermark.gif'); [h w] = size(orig); subplot(121), imshow(orig); subplot(122), imshow(wm, [0 1]); img = bitand(orig, uint8(254*ones(w,h))); img = img + wm; imwrite(img, 'lennawm00.bmp'); I need to hide the watermark into bit5 instead of bit0. Can anyone help me out please?

Answer:
is the image yours??? and therefore the watermark is yours??? if not, then any changes you make are considered illegal and you could find someone taking legal action against you...
