Image processing apparatus, image processing method, and medium that determine whether a candidate region of a specific region in divided images forms the specific image, based on shape information

Abstract

An image processing apparatus includes an acquisition unit to acquire a plurality of divided images from one image. The divided images that neighbor one another do not have an overlapping region. An extraction unit extracts a candidate region of a specific region in the divided image. In a case when candidate regions extracted by the extraction unit neighbor one another at the boundary between the divided images that neighbor one another, a combining unit combines shape information of the candidate regions that neighbor one another. A determination unit determines whether the candidate regions form the specific region by using the shape information combined by the combining unit.
