A Wavelet-Based Restoration Algorithm of Remote Sensing Images

摘要：

This paper proposes a novel restoration algorithm of degraded images based on hidden MarkOV tree(HMT) and Fourier-wavelet regulariZed deconvolution method.Firstly the degraded imagesare deblurred by Wiener filter in Fourier domain andthen the remained unwanted white Gaussian noises areremoved by HMT method in complex wavelet domain.The simulation iS done for solving the typicalconvolution and noised linear degraded image.And itsresults show that the suggested image restorationmethod pefforms better than common Wienerrestoration method in visual perception and obiectivecriterions.
