Algorithm of multi-transform domain HMT image denosing
多变换域马尔可夫树图像去噪算法*

To overcome the drawback of the preference of one kind of transform used in image denosing a proposed,new multi-level denoising approach based on Contourlet transform and Wavelet transform.Analysed the statistical information of image sparse representation of the wavelet domain coefficients and the Contourlet domain coefficients.Captured the character of more cross-correlations of transform domain coefficients between two neighboring scales in the HMTmode.The first image denosing was used by wavelet domian ...
