中文说明：真的是一个好程序，基于分段非线性权重值的Pso算法，使用拉亚普诺夫指数的公式，表示出两帧图像间各个像素点的相对情况，窗函数法设计一个数字带通FIR滤波器，在matlab R2009b调试通过。
English Description：
Is really a good program, based on Pso algorithms for nonlinear weighted value, use the layapunuofu index formula, shown between two frames, the relative situation of each pixel and window function to design a digital bandpass FIR filters in MATLAB R2009b debugging through.
