包括广义互相关函数GCC时延估计，对信号进行频谱分析及滤波，表示出两帧图像间各个像素点的相对情况，主要是基于mtlab的程序，添加噪声处理，使用混沌与分形分析的例程。- Including the generalized cross-correlation function GCC time delay estimation, The signal spectral analysis and filtering, Between two images showing the relative circumstances of each pixel, Mainly based on the mtlab procedures, Add noise processing, Use Chaos and fractal analysis routines.
