摘    要:从原装订本上扫描文件页面往往会导致扫描图像扭曲的情况。该文简要先介绍了SFS方法及分类。然后提出从技术的角度看利用SFS重构扫描图像这一问题。在现实环境中扫描图像有如下特征:1)一个靠近的移动光源;2)Lambertian式光反射;3)文件偏斜。然后利用基于去除灰度和去除变形模式的方法来恢复扫描文件图像。用以重构书曲面的图像,恢复扫描图像。

关 键 词:SFS  图像恢复  图像变形  图像扭曲

Abstract:Scanning a document image from a bound volume often results in distortions in the scanned image.With a brief introduction of Shape from Shading (SFS method) and its classifications, this paper firstly discusses restoration of document image through SFS method from a technical point of view. Scanning document image in real-world environment is characterized by 1) a proximal and moving light source, 2) Lambertian reflection, 3) document skew. Then restore the scanned document image using a shpe based on deshaping and dewarping models.
Keywords:SFS (Shape from Shading)  image restoration  image warping  image distortion
