- W2356407126 abstract "A new erasable watermark algorithm based on prediction error difference expansion of color components is proposed.The algorithm disperses smaller expansion to two components,and utilizes the histogram modification to embed additional information.The embeded point is determined by the quantity of unexpandable difference.The keyword is used to determine the watermark signal and embedding position,and the keyword mechanism can assure very good security for the watermark.The experiments show that the algorithm can assure good imperceptibility for watermarked image and the image can be restored losslessly after the watermark is erased." @default.
