巴特沃斯和切比雪夫低、带通滤波器matlab程序，能播放、读取音乐，加噪，滤噪等。画出加噪前、加噪后、滤波后波形。(Butterworth and Chebyshev low, band-pass filter matlab procedures, can play music, reading, adding noise, filtering etc.. Before the addition of noise, plus noise, after the filter waveform.)

对运动目标进行区域标记以后，去掉小面积的连通区域来消除噪声。(After the moving target region mark, remove a small area of ​ ​ regional connectivity to eliminate noise.)

XY_DISPLAY is a MATLAB program which reads a set of 2D points from a file and plots them in the MATLAB graphics window. The file containing the point coordinates is in the XY format.

比较了几种经典的LMS自适应滤波算法，很清楚地看出在低信噪比下各算法的性能( It compared several classical LMS adaptive filtering algorithm,)
