Hyper error map based document stitching
Chengwu Cui · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2010
The hyper error map is proposed as a metric to guide selection of stitch seam to minimize and avoid document stitching artifacts. An efficient hyper error map computation scheme is also shown with edge filtering. Examples of actual stitching artifacts are presented and used to prove the effectiveness of the hyper error map. The hyper error map is further discussed in relation to the hyperacuity of the visual system, which indicates that other aspect of human perception should also be incorporated in visual modeling for image processing.
