A chaos variation evolution programming and it's application in digital watermark
Liu Li · Microcomputer Information · 2009
The existing digital watermark algorithms are all seek the embedding position according to the human vision model theory. In view of the question,this article proposes an intelligent embedding algorithm based on mutative scale chaos evolution programming. Based on the chaos sequence characteristic,the proposed algorithm introduces chaos into the variation operator of the evolution programming and seeks the embedding position. Theory analysis and experiment are presented to show that this algorithm can seek the best embedding position auto-adaptively. Thereby,the destruction for the original image is reduced to the minimum because of the watermark embedding.
