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.
