If you just need to correct the rotation of the document use: Alyn or deskew 3. While existing methods have improved by leveraging text line awareness, they typi- cally focus only on a single horizontal Document image dewarping using text-lines and line Segments Abstract Conventional text-line based document dewarping methods have problems when handling complex layout and/or very few text Document image dewarping is a crucial step in the digitization process, as it aims to remove the distortions induced by challenging The control points and reference points are composed of the same number of vertices and describe the shape of the document in the image before and after rectifying, respectively. Document dewarping has made great progress in recent years, however it usually requires huge document pairs with pixel-level annotation to learn a mapping function. In contrast to most current works adopting a two-stage pipeline Document dewarping is crucial for many applications. This property aligns with the inherent axis-aligned nature of the discrete grid geometry in Pipeline of DocReal, a robust document dewarping approach of real-life images using attention-enhanced control point (AECP). 本文简要介绍 ACM MM 2022 录用论文“Marior: Margin Removal and Iterative Content Rectification for Document Dewarping in the Wild”的主要工作。该论文针对现有的矫正方法只能在紧密裁剪的文档图 1 核心思想 论文： Document Dewarping with Control Points 代码： https://github.
