Multiview Rectification of Folded Documents.
IEEE Transactions on Pattern Analysis and Machine Intelligence(2018)
摘要
Digitally unwrapping images of paper sheets is crucial for accurate document scanning and text recognition. This paper presents a method for automatically rectifying curved or folded paper sheets from a few images captured from multiple viewpoints. Prior methods either need expensive 3D scanners or model deformable surfaces using over-simplified parametric representations. In contrast, our method ...
