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.

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
