各种去噪方法，主要是半软阈值去噪，广义阈值函数去噪，Donoho阈值或Birge-Massart策略及软阈值或硬阈值函数进行去噪。对灰度和彩色图像均可-Various denoising methods are mainly semi-soft threshold denoising, generalized threshold function denoising, Donoho threshold or Birge-Massart strategy and soft threshold or

小波阈值滤波去噪算法中，使用的软硬阈值函数、改进半软阈值函数及示例(In wavelet threshold filtering denoising algorithm, the soft and hard threshold function, improved semi soft threshold function and examples are used)
