摘    要:扫描书籍时,因为书脊部分远离扫描平面,扫描得到的图像会有变形、明暗不均、模糊等缺点,针对这个问题,在分析书籍空间形状模型的基础上,提出了基于图像边缘提取、线性图像变换和分片直方图修正的综合解决方法.实验结果表明,该方法能够快速、准确地解决书籍扫描图像存在的变形和明暗不均问题.

关 键 词:图像处理  图像变形  边缘提取  直方图修正

Abstract:Due to its spine the book can not be set as close to the flat bed of the scanner as a paper. As a result, the obtained image will suffer from distortion, variant brightness and blurring. In this article a method based on edge extraction, linear image transformation and histogram modification is proposed to address the mentioned problem. Experimental results show that the proposed method can correct the image distortion and brightness variance problems quickly and precisely.
Keywords:image processing  image distortion  edge extraction  histogram modification
