摘要
基于文字识别系统中图像的自身特点 ,提出一种对于小角度倾斜 (± 5°以内 )文本图像的倾斜角度快速计算及校正算法 ,有效克服了几何失真对文字识别系统的影响 .通过采用逐段整块搬移的线性校正方法 ,成倍提高了校正算法的执行速度 .
On the basis of the features of the text image in character recognition system, a new algorithm is put forth to detect and rectify the slanting image. By using the linear whole block moving method in each vertical segment, this algorithm has effectively overcome the unfavorable fuzzy influence brought by geometrical rectification, and greatly enhanced the executive speed of slanting rectification. Its implementation is also given.
