Abstract
A text image correction method and a corresponding text image correction apparatus. Frequency information of a row-direction cumulative curve used by the method is sensitive to an error between a compensation angle for a tilt angle and a real tilt angle, and the method thus has good robustness. The method can accurately estimate the compensation angle for a tilt angle and correct a tilted text image. The method and apparatus can be applied to scenarios such as image pre-processing, automatic compensation for angles of scanned text images, automatic compensation for tilt angles of mobile phone photos.
