Watermarking Algorithm based on Contourlet Transform And Human Visual Model

摘要：

The translation-invariant circular symmetric contourlet transform(TICSCT) is a multiscale,multidirection and shiftinvariant overcomplete transform. The paper proposes a blind watermarking algorithm in the TICSCT domain. A simple but effective human visual model in TICSCT domain is described.By modelling watermarking as a communication process. The experimentations show that this domain has higher capacity than the wavelet (include complex wavelet and real wavelet) and spatial domains. Watermarking algorithm based on TICSCT improves the robustness of watermark at gaussian white noise attack. Hence that TICSCT provide a potentially good domain for watermarking.
