- W2349286054 abstract "A watermarking algorithm based on discrete wavelet transform and chaotic sequence is proposed, with both of robustness and concealment taken into account. In this method, a bi-chaotic sequence generated from logistic is adopted as the watermark and the representative gray level images are adopted as the original image to be embedded in. Firstly the resolution wavelet decomposition is used towards the original image, and then the watermark data is embedded into the original image through modifying the intermedi-ate frequency wavelet coefficients of original image a correlation detect of multi-sequence method is used in the according extracting procedure to enhance the right rate of watermark detecting even though the watermark is affected in the signal processing the method still can detect it." @default.
