摘要
Abstract
An image watermarking method based on image texture,random transformation(Gaussian distribution) and Logistic mapping is proposed in this paper.In this algorithm,chaos transform is used together with random mapping to encrypt watermark in order to enhance the security.When embedding watermarking,the original image separates the texture regions by using the Prewitt operator,and different textures are embedded by different strengths of watermark.A lot of experiment are done,and results show the invisibility and robustness of this method.关键词
