| 摘要 |
Aspects of the present invention are related to systems, methods and apparatus for correcting artifacts in a camera-captured document image and, in particular, to methods, systems and apparatus for correcting perspective distortion in the camera-captured document image. Multiple rectification hypothesis may be generated and verified based on a plurality of geometric rectification quality measure values. In particular, a first rectification hypothesis may be associated with a first bounding quadrilateral determined by estimation of horizontal and vertical vanishing information. |
