| 摘 要： | 该文提出了一种基于噪声允许的信道选择方案,根据图象自身特点,结合人眼视觉模型和噪声可见性函数,找出了在满足不可见性条件下每个信道可嵌水印的最大强度。在应用香农信道理论进行容量估计的同时,协调好了鲁棒性、不可见性、容量三者的关系。

| Abstract: | An channel selection method based on tolerable noise was put forward, from the image itself future, every channel's maximum watermark amplitude can be obtained while meeting conditions of invisibility as well as combining with human visual system and noise visibility function. The robustness, the invisibility and capacity can be balanced well while the Shannon capacity theory estimate the capacity. |
