摘要
提出了一种新的算法,有效地模拟了人眼对图像中“细节”与“纹理”的区分,从而可以在图像的纹理中嵌入较强的水印,在图像的细节中嵌入较弱的水印.该算法在保证水印的不可见性和鲁棒性的同时,有效地保护了图像的细节信息.
According to the characteristics of detailed still image, a new algorithm is proposed in order to simulate a complex process in which the eyes differentiate between detail and texture of an image. With this algorithm, details of image can be protected from being damaged by the watermark and more watermarks can be embedded into the textured areas.
