Image denoising based on integer DCT and block-matching
Yao Nai-men · 2015
Image denoising is a traditional point in the field of image processing and video processing,and despite the traditional denoising in spatial domain,denoising methods in frequency domain have achieved significant results. The paper proposed a color image denosing method in spatial domain based on block-matching in frequency domain. Applying integer DCT on achieved matched blocks after blocking-matching is prepared for denoising in frequency. After denoising,through integer inverse DCT the results in spatial domain are presented. The method proposed gets efficient processing and achieves equal denoising results,which performs well on color images denoising.
