An Improved Wavelet Digital Watermarking Software Implementation
There are quite a number of researches in proposing digital image watermarking using Discrete Wavelet Transform (DWT). However, it is clearly observed that each of them is individually distinctive in terms of its scopes and applications. In this paper, a proposed system was thoroughly explained....

| description | There are quite a number of researches in proposing
digital image watermarking using Discrete Wavelet Transform
(DWT). However, it is clearly observed that each of them is
individually distinctive in terms of its scopes and applications. In
this paper, a proposed system was thoroughly explained. It
includes general work flow, proposed algorithms for both
original method and improved method, which were named as
subband matching and selective subband matching, respectively
and various attacks performed for evaluation. Modification was
made to the algorithms where only selected matching subbands
were used in embedding and extracting the watermark in this
improved method. These methods were compared and tested
against attacks using standard benchmark, Stirmark.
Experimental results of the proposed methods’ performance were
analyzed using Peak Signal to Noise Ratio (PSNR) calculations
and Structural SIMilarity (SSIM) index for watermark
imperceptibility and robustness, respectively. The improvement
could be seen in quality of the watermarked image
(imperceptibility) and of extracted watermark (robustness). |
