变形文档图像的矫正方法研究

针对文档表面易发生弯曲变形从而影响文档图像识别率这一问题,通过建模恢复文档表面形状,并运用参数化插值的方法实现了变形文档图像的矫正。本文讨论了基本理论及方法,并对算法的设计及实验中开发的平台进行了介绍,实验数据表明本方法可以有效的实现文档图像的矫正。

Research on Rectification Method of Curved Document Image

For the problem that the document surface is curved and the recognition rate is influenced, this paper proposes a way by modeling and retrieving the surface shape, and then the document image rectification is implemented by using parameterization inter-polation. In this paper,basic principal as well as approaches are discussed, and the arithmetic design as well as experiment developed platform are introduced. The experiment data show that the approach can rectify the document image efficiently.
