M带小波的子带自适应阈值除噪算法

在广义高斯分布（Generalized Guassian Distribution，GGD）模型最优软阈值的基础上，提出了一种基于M带小波变换的子带自适应图像除噪阈值确定方法，在阈值确定中，考虑了尺度因子、子带大小等因素的影响。采用软阈值除噪，算法简单实用。实验表明，对纹理丰富的图像，该文提出的除噪方法效果优于目前流行的其他算法。

Subband adaptive threshold algorithm for image denoising on M-band wavelet transform

This paper proposes an adaptive threshold estimation algorithm for image denoising based on M-band wavelet transform, which comes from the ideal of the optimal soft threshold using Generalized Guassian Distribution(GGD)model.In the threshold estima- tion,the influences of scale factor and suband length are considered.Denoise using soft threshold is simple and convenient.Experi- mental results of texture images denoising show that the proposed method outperforms other state-of-the-art techniques.
