(PDF) Dewarping of document images using coupled-snakes
This paper proposes a segment-free method for geometric rectification of a distorted document image captured by a hand-held camera. The method can recover the 3D page shape by exploiting the ...
Geometric rectification of document images using ...
Tan et al. further extended such method by first designing 3D geometric model and 3D optical model to reconstruct the 3D shape of the book surface, and then using de-shading and de-warping models to restore the scanned document images. However, we have to point out that these methods can hardly be used to handle distorted documents captured ......
Digitally reconstructing the Great Parchment Book: 3D ...
These line tracing methods work well on documents with clear text and good image contrast. Schneider et al. and Tian and Narasimham (2011s) reconstruct the shape of smoothly folded pages by detecting horizontal line directions and vertical strokes in the text, de-warping images of textual documents by estimating the 3D surface of the document ......
