Document Image Rectification using Advance Knowledge of 3D Deformation
Summary
As a promising approach for high-speed, non-destructive and easy-to-use book digitization, Book Flipping Scanning which scan large stacks of paper, while the pages are flipped continuously without stopping on each page, has been proposed. In this technology, the image rectification is required because the captured document images are distorted because of the paper deformation. As one of the solutions, there is a conventional technique based on the estimation method of non-rigid surface deformation using developable surface model. However, it is difficult to design a general developable surface model which can express any deformation. This problem degrade the quality of the digitization. In this research, we propose a new document image rectification using advance knowledge of 3D deformation without relying on the model-based approach.
