Method and apparatus for image positioning processing

Abstract

Radiation images recorded serially on a plurality of sheets overlapping partially are positioned accurately. An image positioning processing apparatus comprises overlap area detection means for detecting an overlap area between two radiation images overlapping partially, rotation correction means for rotating, based on the overlap area, a lower image out of the two images, template setting means for setting a plurality of templates within the overlap area of the lower image, rank setting means for setting a reliability rank for each of the templates, matching position determining means for determining, based on the ranks of the templates, a matching position at which an image portion within each of the templates almost matches up with an image portion within the overlap area of an upper image, and positioning means for carrying out positioning of the two images based on the matching position having been determined.
