Description: 一种新的图像脆弱水印算法李亚琴 ，孙星明 ，杨恒伏(1．苏州市职业大学，江苏苏州215104；2．湖南大学计算机与通信学院，湖南长沙410082)摘要：提出一种基于小波变换和QR分解的图像脆弱水即方法。嵌入水印时，首先对原始图像进行三级小波分解，然后提取第三级低频子带的边缘特征，同时对此边缘特征和第三级垂直高频子带进行QR分解，用边缘特征的一部分分解结果替换垂直高频子带分解结果的相应部位来嵌入水即，最后进行小波逆变换得到嵌入水印的图像。图像认证时，首先对观测图像进行三级小波分解，第三级垂直高频子带与低频子带边缘特征的QR分解结果进行比较，就可以准确认证图像是否经过攻击，并可以精确定位受攻击的部位。实验结果表明此方法的有效性和可行性。-a new image fragile watermarking algorithm Ya-Qin Li, Sun Xingming, Heng Yang Fu (1. Suzhou City Vocational University, Suzhou City in Jiangsu 215104; 2. Hunan University College of Computer and Communication, Changsha, Hunan 410082) Abstract : A wavelet transform based on QR decomposition and the image that the fragile water ways. Embedded watermark, the first of three original image wavelet decomposition, and then extract the third level sub-band edge features, Meanwhile this edge features and third-vertical high-frequency band for QR decomposition, Edge feature with the results of the replacement part of decomposition vertical high-frequency subband results to the corresponding parts of the water that is embedded. Finally inverse wavelet transform embedded watermark images. Image Authen Platform: |
