Paper Abstract

A new scheme to search perceptually significant wavelet coefficients for effective digital watermark casting is proposed in this research. An adaptive method is developed to determine significant subbands and select a number of significant coefficients in these subbands. Experimental results show that the cast watermark can be successfully retrieved after various attacks including signal processing, geometric processing, noise adding, JPEG and wavelet-based compression methods.
