We broadly define filters\nas operations to smooth images or to produce layers via global or local\nalgorithms. And we raise the intriguingly problem if they are reservable to the\nstatus before filtering. To answer it, we present a novel strategy to\nunderstand general filter via contraction mappings on a metric space. A very\nsimple yet effective zero-order algorithm is proposed. It is able to\npractically reverse most filters with low computational cost. We present quite\na few experiments in the paper and supplementary file to thoroughly verify its\nperformance. This method can also be generalized to solve other inverse\nproblems and enables new applications.","url_abs":"http://arxiv.org/abs/1704.04037v1","url_pdf":"http://arxiv.org/pdf/1704.04037v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"zero-order-reverse-filtering","repo_url":"https://github.com/jiangsutx/DeFilter","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
