自己本机测试最快时60帧/秒,局域网传输只测试一次,结果很让我失望,原因不明~~~~ 说下我的思路过程(我认为过程很重要!) 分块比较+压缩传输与以前那个内存流比较的优缺点: 内存流比较能找到最精确的找到图片差异,但每次都要压缩相同大小的数据,大家可以测试下,那个算法传输瓶颈是压缩算法,最费时间和CPU 分块比较+压缩传输能有效的减少压缩数据量,但缺点也很明显,比较图片的效率肯定没内存流比较高,要加快传输只能找到更好的算法 我选择的是后者,开始的时候是直接把截下来的图片分成n块,然后逐块和上一个图片比较,不同就放到流中压缩传送,不过写完测试时很是郁闷,Cpu占用不说,在自己电脑上根本就突破不了16帧,当时就苦想能节约时间的方法(当时做梦都在想^.^),终于在一次被吵醒后来了灵感,每次都要把图片分成n块,这也很占时间啊,有没有更好的办法呢?觉也睡不着了... 具体实现就看代码吧^_^-Their own tests of this machine, when the fastest 60 frames/sec, LAN transmission test only once, the result will let me down, for reasons unknown ~ ~ ~ ~ wrote down my thought process (I think the process is very important!)

基于奇异值分解的人脸识别方法 梁毅雄 龚卫国 潘英俊 李伟红 刘嘉敏 张红梅 提出了一种将傅里叶变换和奇异值分解相结合的人脸自动识别方法.首先对人脸图像进行傅里叶变换,得到其具有位移不变特性的振幅谱表征.其次,从所有训练图像样本的振幅谱表征中给定标准脸并对其进行奇异值分解,求出标准特征矩阵,再将人脸的振幅谱表征投影到标准特征矩阵后得到的投影系数作为该人脸的模式特征.然后,对经典的最近邻分类器算法进行了改进,并采用模式特征之间的欧式距离作为相似性度量,从而完成对未知人脸的识别.采用ORL (Olivetti Research Laboratory)人脸库对本文提出的人脸识别方法进行验证,获得了100.00 的识别率.实验结果表明,本方法优于现有的基于奇异值分解的人脸识别方法,且对表情、姿态变换等具有一定的鲁棒性. -Face recognition based on singular value decomposition method Deliberate simultaneously Gong Weiguo Li Wei Hung Stephen Lau, Hong-Mei Zhang Ying-Jun Pan Paper, a Fourier transform and singular value decomposition of the combination of automatic face recognition.
