Although many methods have been proposed recently, they often struggle to achieve satisfactory results when confronted with intricate document structures and higher degrees of deformation in real-world scenarios. Our main insight is that, unlike other document restoration tasks (e.g., deblurring), dewarping in real physical scenes is a progressive motion rather than a one-step transformation. Based on this, we have undertaken two key initiatives. Firstly, we reformulate this task, modeling it for the first time as a dynamic process that encompasses a series of intermediate states. Secondly, we design a lightweight framework called TADoc (Time-Aware Document Dewarping Network) to address the geometric distortion of document images. In addition, due to the inadequacy of OCR metrics for document images containing sparse text, the comprehensiveness of evaluation is insufficient. To address this shortcoming, we propose a new metric \u2013 DLS (Document Layout Similarity) \u2013 to evaluate the effectiveness of document dewarping in downstream tasks. Extensive experiments and in-depth evaluations have been conducted and the results indicate that our model possesses strong robustness, achieving superiority on several benchmarks with different document types and degrees of distortion.<\/jats:p>","DOI":"10.3233\/faia250803","type":"book-chapter","created":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T09:42:40Z","timestamp":1761126160000},"source":"Crossref","is-referenced-by-count":0,"title":["TADoc: Robust Time-Aware Document Image Dewarping"],"prefix":"10.3233","author":[{"given":"Fangmin","family":"Zhao","sequence":"first","affiliation":[{"name":"Institute of Information Engineering, Chinese Academy of Sciences"},{"name":"School of Cyber Security, University of Chinese Academy of Sciences"}]},{"given":"Weichao","family":"Zeng","sequence":"additional","affiliation":[{"name":"Institute of Information Engineering, Chinese Academy of Sciences"},{"name":"School of Cyber Security, University of Chinese Academy of Sciences"}]},{"given":"Zhenhang","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Information Engineering, Chinese Academy of Sciences"},{"name":"School of Cyber Security, University of Chinese Academy of Sciences"}]},{"given":"Dongbao","family":"Yang","sequence":"additional","affiliation":[{"name":"Institute of Information Engineering, Chinese Academy of Sciences"}]},{"given":"Yu","family":"Zhou","sequence":"additional","affiliation":[{"name":"VCIP & TMCC & DISSec, College of Computer Science & College of Cryptology and Cyber Science, Nankai University"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","ECAI 2025"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA250803","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T09:42:40Z","timestamp":1761126160000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA250803"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,21]]},"ISBN":["9781643686318"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia250803","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10,21]]}}}
