Document Dewarping
Transforming a photographed or scanned document to correct geometric distortion, such as curved page surfaces or perspective effects. Unlike simple deskewing, it can change positions nonuniformly across the image. The transformation needs validation because a flatter appearance does not prove all text was preserved.
