1. 本程序使用PCA算法对训练图像降维,得到特征图像;
2. 将每一幅图片与平均图像的差值投影到特征向量空间;
3. 计算训练图片投影两两之间的最大欧氏距离distance_max;
4. 将测试图片也投影到特征向量空间,计算它与所有训练图像投影的最小欧氏距离distanceST_min。
5. 设定判别阈值(设为0.3*distance_max,此为测试得到的经验值,不同阈值将影响判别结果)。当distanceST_min>0.3*distance_max时,则认为测试

视频水印技术是利用某些特定的算法把一些标志性的水印信息嵌入到视频当中,它用于视频的版权保护,是信息隐藏技术领域研究的一个重要方向。本课题通过分析视频水印技术的发展背景、应用领域、发展现状及其相关理论知识,提出了一种在视频关键帧中嵌入水印的算法。该算法首先利用Arnold置乱技术对水印图像进行加密预处理,然后根据欧式距离法提取出视频关键帧,最后通过LSB算法在关键帧中实现水印的嵌入和提取。处理过的关键帧合成视频中后仍然可以正常播放,且不会被人的感知系统察觉或注意到。实验表明该算法合理易实现。-Vi
