本文选用了背景减法、帧间差分法和光流法。背景减法是通过将当前帧与背景帧相减得出灰度差值并将此差值与阈值比较判断是否有运动目标。-This paper chose the background subtraction and frame difference method and optical flow method.Background subtraction is through to the current frame and background frame subtraction gr

基于谱减法的语音增强在MATLAB实现源程序 不错的源码 很好-Based on the spectral subtraction speech enhancement in the MATLAB source code for the good of the source code is very good
