Memetic algorithm-based image watermarking scheme

Abstract

Watermarking technology is the most efficient way to protect the ownership of multimedia data. In this paper, a novel image watermarking scheme using the Discrete Wavelet Transform (DWT) and memetic algorithm (MA) is introduced. The watermark is embedded to subband coefficients of subimage which is extracted from the original image by using DWT, and watermark extraction is efficiently performed via memetic algorithm. Experimental results show that the proposed watermarking scheme makes an almost invisible difference between the watermarked image and the original image, and is robust to common image processing operations. © 2008 Springer-Verlag Berlin Heidelberg.
