Documents typically have a constant colored background; based on this observation, we propose a technique to estimate background and text color in local image blocks. We match these local background color estimates to a global reference to generate a shadow map. Correcting the image with this shadow map produces the final unshadowed output. We demonstrate that our algorithm is robust and produces high-quality results, qualitatively and quantitatively, in both controlled and real-world settings containing large regions of significant shadow.","url_abs":"https://link.springer.com/chapter/10.1007/978-3-319-54187-7_12","url_pdf":"https://link.springer.com/chapter/10.1007/978-3-319-54187-7_12","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":"removing-shadows-from-images-of-documents","repo_url":"https://github.com/tigerdeeda/Removing-Shadows-from-Images-of-Documents-by-Steve-Bako","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null},{"paper_slug":"removing-shadows-from-images-of-documents","repo_url":"https://github.com/CV-Reimplementation/TraditionalDocumentShadowRemoval","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"document-shadow-removal","task_name":"Document Shadow Removal"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
