说明：  本例是一个采用帧差法的运动跟踪代码，其对背景不变的单目标有较好的处理(This example is a frame difference method using the movement of the tracking code, change the background of its single objective better deal)

说明：  Singular Spectrum Decomposition，即奇异谱分析，广泛应用于信号识别与预测。(Singular Spectrum Decomposition)

从信号处理的角度讲，小波(变换)是强有力的时频分析(处理)工具，是在克服傅立叶变换缺点的基础上发展而来的，所以从信号处理的角度认识小波，需要傅立叶变换、傅立叶级数、滤波器等的基础知识。 (From signal processing perspective, the wavelet (transform) is a powerful time-frequency analysis (processing) tool is to overcome the shortcomings on the basis of Fourier transform evolved, so from the perspective of understanding of wavelet signal processing need to Fourier transform, Fourier series, filters and other basic knowledge.)
