语音增强算法，该算法描述了经典谱减法的计算流程，结果用语谱图加以显示。,Speech enhancement algorithm, which describes the classical spectral subtraction in the calculation process, the results of the term spectrum to be displayed.

自己编写的用谱相减,最小均方和维纳滤波实现语音增强的matlab文件(Write your own using spectrum subtraction, wiener filtering and minimum mean square of speech enhancement matlab files)

MATLAB 里基于背景差法提取前景目标，已经试过，可以提取(Foreground target extraction based on background subtraction)
