中文摘要：
提出了一种基于视觉注意机制的图像感兴趣区域（regions of interest，ROI）纹理块鲁棒水印方案，用视觉注意模型计算出图像的显著图，基于显著图坐标和图像纹理区，采用调整Tchebichef矩系数的方法对感兴趣区域进行水印的嵌入，用于保护图像的感兴趣区域。该算法实现了对图像感兴趣区域的有效自动分割，提高了计算机图像分析与处理的有效性和针对性，对图像压缩、滤波、噪声添加、背景替换以及恶意剪切等攻击均具有很强的鲁棒性。
英文摘要：
A robust digital image watermarking scheme based on the mechanism of visual attention is presented. By the models of visual attention it can get the regions of interest （ROI） of the cover image, and then hide the watermarks in the texture block of the ROI. Firstly, the saliency map of the cover image by the models of visual attention is gotten. And secondly, based on saliency map and texture block, the watermarking is embed into the regions of interest by adjusting the coefficient of Tchebichefmoment. This algorithm realizes automatically segment the ROI of the image, enhances the effectiveness and implements the purpose of image analysis and processing, and has a good robust to image compression, filtering, adding noise, background replacement and malicious cut, etc.
