Özet:

 

The paper presents an improved digital image watermarking algorithm by   incorporating the discrete Fourier transform (DFT) and singular value   decomposition (SVD). The Fourier transformed carrier image is decomposed   into four different frequency subbands by the proposed onion peel   decomposition (OPD) algorithm and the SVD-based watermarking scheme is   applied to attach the transformed watermark in all four carrier subbands.   The proposed inverse OPD algorithm together with inverse DFT is utilized to   reconstruct the watermarked image from the frequency blocks. The watermark   extraction algorithm is simple and it performs the inverse of watermarking   process. The experimental analysis on different images shows that the   proposed algorithm produces good quality watermarked images. The watermarks   extracted from watermarked images inflicted with potential attacks are also   of better perception quality than those produced by other prominent   algorithms in terms of subjective and objective metrics.
