Knaus, ClaudeClaudeKnausZwicker, MatthiasMatthiasZwicker0000-0001-8630-55152024-10-242024-10-242015https://boris-portal.unibe.ch/handle/20.500.12422/141342We propose dual-domain filtering, an image processing paradigm that couples spatial domain with frequency domain filtering. Our dual-domain defined filter removes artifacts like residual noise of other image denoising methods and compression artifacts. Moreover, iterating the filter achieves state-of-the-art image denoising results, but with a much simpler algorithm than competing approaches. The simplicity and versatility of the dual-domain filter makes it an attractive tool for image processing.en000 - Computer science, knowledge & systems500 - Science::510 - Mathematicsarticle10.7892/boris.8112410.1137/140978879
