Simple Watermarking using Wavelet transform

Implementing Watermarking using discrete 2-D wavelet transform.

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.

hello
i need your help in performing this article "A Wavelet-Based Watermarking Algorithm for
Ownership Verification of Digital Images" .
plz help me i need to your guide very much

good, but extraction procedure was not included.

thanks, could someone tell where i can find the extraction process of this 2-D dwt watermarking & also reversible watermarking using histogram shifting source codes

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
