Image denoising using multiple compaction domains

  title={Image denoising using multiple compaction domains},
  author={Prakash Ishwar and Krishna Ratakonda and Pierre Moulin and Narendra Ahuja},
We present a novel framework for denoising signals from their compact representation in multiple domains. Each domain captures, uniquely, certain signal characteristics better than others. We define confidence sets around data in each domain and find sparse estimates that lie in the intersection of these sets, using a POCS algorithm. Simulations demonstrate the superior nature of the reconstruction (both in terms of meansquare error and perceptual quality) in comparison to the adaptive Wiener… CONTINUE READING
