针对高斯白噪声，高斯色噪声以及色噪声中常见的粉红色噪声进行了降噪处理，并与相关系数法、小波软阈值降噪方法进行了对比- Gaussian white noise, Gaussian colored noise and pink noise have been　processed to verify the validity of the algorithm. we also compared the proposed method with the correlation coefficient method and wavelet soft threshold noise reduction methods.
