均值背景建模，包含视频！效果还可以，背景建模的还是不错的！(Mean background modeling, including video! Effect can be, background modeling is good!)

已知两点经纬度，计算两点之间距离。 利用大地坐标！(The known longitude and latitude calculate the distance )

运行多径衰落信道，可以通过MATLAB仿真出来的程勋(Running multipath fading channels)

谐波恢复的ARMA建模算法(基于SVD-TLS)（张贤达《现代信号处理》）。当谐波信号为复谐波的时，该算法仍然适用。但该程序中没有给出具体的实现。(Harmonic Retrieval of ARMA modeling algorithm (based on the SVD-TLS) (Xian Tatsu Modern Signal Processing ). When the harmonic signal for the resumption of harmonics, the algorithm still applies. However, the procedure did not give a concrete realization.)
