ABSTRACT:
Matching between a reference image and an input image is performed without relying on specific elements such as line segments or tables. An edge image is generated from the reference image and divided into small blocks, and search range and search priority of each small block are determined and stored in a storage device. When an input image is input, an edge image thereof is generated. The small blocks in the reference image are retrieved in order of priority, and matching with the input image is judged. When the corresponding position of one small block is determined, the search range and search priority for other small blocks not yet judged for matching are updated on the basis of the determined corresponding position.
