Iterated Denoising and Fusion to Improve the Image Quality of Wavelet-based Coding

摘要：

An iterated denoising and fusion method is presented to improve the image quality of wavelet-based coding. Firstly, iterated image denoising is used to reduce ringing and staircase noise along curving edges and improve edge regularity. Then, we adopt wavelet fusion method to enhance image edges, protect nonedge regions and decrease blurring artifacts during the process of denoising. Experimental results have shown that the proposed scheme is capable of improving both the subjective and the objective performance of wavelet decoders, such as JPEG2000 and SPIHT.
