File Information
Description

Performs watermarking of the input image by decomposing the image using haar wavlet. Noise generated with normal distribution is used as the key and is added to the input image to obtain the watermarked image.

Required Products Image Processing Toolbox
Wavelet Toolbox
MATLAB release MATLAB 6.5 (R13)

good. the program only introduces a watermark into the image but the detection is not mentioned. it would be excellent if the detection algorithm was given

Hi.I was wondering if someone could tell me where i can find reversible watermarking using histogram shifting source codes.It would me nice if you could help me out regarding the same.Thanks.
