针对基于数码相机拍摄的小型文档图像,提出一种集成型的小型文档图像透视变形校正方法.利用小型文档本身面积小,文字数少,版面较复杂的特点,通过彩色图像分割提取小型文档的外边缘并结合小型文档内部的文字信息进行校正.实验表明,该方法能够有效地对小型文档图像进行快速准确的校正.
Abstract
In this paper, an integrated perspective distortion correction method is proposed aiming at the smallsquare document images acquired by the camera. The characteristics of smallsquare documents-small area, fewer words and complicated layout, boundaries of smallsquare document region extracted by color image segmentation methods as well as the text information in the document are used to correct the distortion. Experimental results show that this method can rectify the smallsquare document image effectively.
