PSOt

This code shows in a simple way the implementation of 2 dimention finite difference time domain simulation. We also implement perfectly match layer at the border.

直方图提取函数，用于人脸识别中，输入一幅图像，函数内部对输入图像做短时傅里叶变换，得到四幅幅度图，再求四幅图的直方图特征，合并后输出(Histogram extraction functions for face recognition, the input image, the input image inside the function to do short-time Fourier transform, the four magnitude diagram, and then seek four graph histogram feature, the combined output)
