re synthesize the speech signal

chan vese segmentation

通过MATLAB程序，进行语音信号处理里面的基于MMSE的谱减法增强处理程序，程序消除噪声的效果是现有算法的3dB，特别的对于 RalzCK格式和 OfkGJZu 格式的语音处理效果很好。(By MATLAB program for speech signal processing inside the MMSE-based spectral subtraction enhancement program, the program to eliminate the effect of noise existing algorithms 3dB, special effects for speech processing RalzCK format and OfkGJZu format well.)

说明：  变分模态分解方法能够使一个多频带的故障信号，分解出具有单个频带的子信号，然后使用共振解调方法可实现故障信号的诊断。(VMD method can decompose a multi band fault signal into a single band sub signal, and then use resonance demodulation method to realize fault signal diagnosis.)
