Parsimony-based algorithms have shown great success on images and\nvideos where data points are sampled on a regular Cartesian grid. We propose an\nadaptation of these techniques to irregularly sampled signals by using\ncontinuous dictionaries. We present an example application in the form of point\ncloud denoising.","url_abs":"http://arxiv.org/abs/1612.04956v2","url_pdf":"http://arxiv.org/pdf/1612.04956v2.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":"cloud-dictionary-sparse-coding-and-modeling","repo_url":"https://github.com/orlitany/Cloud_dictionary","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null},{"paper_slug":"cloud-dictionary-sparse-coding-and-modeling","repo_url":"https://github.com/PeterBeben/continuous-K-SVD","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null},{"paper_slug":"cloud-dictionary-sparse-coding-and-modeling","repo_url":"https://github.com/codearxiv/continuous-K-SVD","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"autonomous-driving","task_name":"Autonomous Driving"},{"task_slug":"denoising","task_name":"Denoising"},{"task_slug":"gesture-recognition","task_name":"Gesture Recognition"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
