一种改进的模拟退火图像盲复原算法 - This is blind image restoration
这就是图像盲恢复。 - By applying generalized gaussian distribution to statistically model the alternating current coefficient of discrete cosine transform , the technology of the blind image watermark is studied and the performance of the new detector is analyzed
摘要根据数字图像离散余弦变换域交流系数的广义高斯分布模型，对盲图像水印技术进行研究，并给出了水印检测器检测性能的理论分析结果。 - The main contributions of this dissertation are : a novel detection strategy in blind image watermarking algorithm generally , the traditional detection strategy corresponding to embedment model i = i + aw has its limitation . first , we treat the watermark information as noise for an image and expand the noise before detection . then , we find the corresponding data in the frequency - domain and adjust them according to our relative minmum principle
为了解决这一问题，我们将嵌入水印图像中的水印信息看作一种噪声，在提取水印前，利用降噪方法得到原始图像的一个逼近，通过和待检测图像的比较，得到含有水印信息的噪声，再将这种噪声信息进行放大，最后利用局部最大的编码原则将水印恢复出来；将改进的水印提取模型应用于基于fourier - mellin变换的盲水印算法，解决了由于插值和多变换造成误差积累而造成很难提取水印这一问题。
