摘要

经典的小波去噪方案仅利用上细节子带估计小波域内的噪声电平。在本文中，我们提出了一种混合的小波图像去噪方法，该方法在自适应边缘保留方案中估计噪声在整个图像像素的空间域上的标准差。然后，使用该估计计算小波系数收缩的阈值。

Wavelet image denoising based spatial noise estimation

The classical wavelet denoising scheme estimates the noise level in the wavelet domain using only the upper detail subband. In this paper, we present a hybrid method for wavelet image denoising in which the standard deviation of the noise is estimated on the entire image pixels in the spatial domain within an adaptive edge preservation scheme. Thereafter, that estimation is used to calculate the threshold for wavelet coefficients shrinkage.
