Abstract

When the printed material is imaged by a monocular digital camera, geometric distortions caused due to folds result in a different appearance from the content of the original printed material. This study aims to reproduce appearance by correction the obtained image. As a proposed method, the geometric distortion is corrected by deforming each local area after dividing the printed material image into local areas. In addition, the brightness change by shading is also corrected.
