Invisible image watermarking by DWT-HUFFMAN-EZW methodology

Abstract

In information security world, invisible image watermarking is the important part. Many invisible image watermarking algorithms fail to achieve the good quality-based watermarking with high security. In this paper, we are working to improve the performance of the invisible watermarking. We are proposing a DWT-EZW-based watermarking. In the results session, we are showing the comparison between DWT-FWHT-SVD and DWT-Huffman-EZW-based watermarking. Comparison is shown for peak signal to noise ratio (PSNR) and mean square error (MSE).
