自适应融合的小波域水印方法
Wavelet Domain Watermark Method with Adaptive Fusion
摘要
Abstract
Digital watermark technique is proposed as a solution for problems of copyright projection. Most of current image watermark schemes embed watermark into host image twice. In these schemes, the values of fusion parameter effects on the visual of exacted watermark information. This paper presents a new method to compute fusion parameter adaptively which can get different result based on different host images, watermark information. It is one important aspect way that it can avoid repeat experiment and estimate of the kind of attack. Experimental results show that the proposed way yield good visual effects.关键词
