(PDF) A Two-Step Dewarping of Camera Document Images
In this Paper, We Proposed a novel algorithm for de-warping of Persian document images captured by the cameras. The aim of de-warping is to remove page distortions and to straighten document ...
(PDF) Rectification of Camera Captured Document Images for ...
Document images captured by a digital camera often suffer from serious geometric distortions. In this paper, we propose an active method to correct geometric distortions in a camera-captured ...
(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 ...
Rectifying the bound document image captured by the camera ...
Digital cameras have become almost ubiquitous and their use for fast and casual capturing of natural images is unchallenged. For making images of documents, how-ever, they have not caught up to flatbed scanners yet, mainly because camera images tend to suffer from distortion due to the perspective and are therefore limited in their further use for archival or OCR....
US20130148861A1 - Systems and methods for video processing ...
For example, camera 20 may be a fish eye or panomorphic lens camera 20 and the captured video may require de-warping. The video processing module 82 may be configured to work with the identification module 70 to resize the captured video based on the sub-portion of the video identified using the interest-ratings of the players 110 .

Current OCR systems do not expect these types of artifacts, and have poor performance when applied directly to camera-captured documents. The goal of page de-warping is to flatten a camera captured document such that it becomes readable by current OCR systems. Responsibilities Studied and developed a complete architecture of the project.
A Theoretical Justification of Warping Generation for ...
Dewarping is a necessary preprocessing step to recognize text from a distorted camera captured document image. According to recent literature, deep le…
