摘要
Abstract
Image watermarking is a technique that can attach hidden data into the image. An image watermarking algorithm based on biorthogonal DWT and image complexity model is proposed in this paper.The image applied biorthogonal DWT to decompose into bands,the best band is embedding with the help of entropy, the best locations in the selected band are found using the image complexity model.Expermiental results show that the proposed algorithm is robust that is evaluated with the aid of different filtering techniques and good results were achieved in all cases.关键词
