代码说明:

创建图像库!这样一来,由于人脸结构的相似性,一旦把这些人脸图像归一化之后,就可以明显的看出,这些人脸图像在高维空间中并不是随机和散乱分布的,而是存在一种规律。在接下来的实验当中,N取128沃们知道,K-L变换方法从本质上来说,就是一种由人脸图像的像素点的灰度级在空间分布时候给你的相关性来决定的。所以,在进行K-L变换之前,沃们需要对人脸图像进行相应的一系列预先处理,以达到位置的校准和灰度归一化的目的。那么接下来沃们先看看图像的归一化,在后面沃们会把归一化的图像应用在K-L变换当中。

    说明:  用LMS算法实现这个自适应均衡器,画出一次实验的误差平方的收敛曲线,给出最后设计滤波器系数。一次实验的训练序列长度为500。进行20次独立实验,画出误差平方的收敛曲线。(LMS algorithm with the adaptive equalizer, draw a square of experimental error convergence curves of the final design of the filter coefficients. An experiment of training sequence length is 500. To 20 independent experiments, to draw square error convergence curves.)
