Abstract
Even if an object to be detected is not remarkable in images, and the input includes images including regions that are not the object to be detected and have a common appearance on the images, a region indicating the object to be detected is accurately detected. A local feature extraction unitextracts a local feature of a feature point from each image included in an input image set. An image-pair common pattern extraction unitextracts, from each image pair selected from images included in the image set, a common pattern constituted by a set of feature point pairs that have similar local features extracted by the local feature extraction unitin images constituting the image pair, the set of feature point pairs being geometrically similar to each other. A region detection unitdetects, as a region indicating an object to be detected in each image included in the image set, a region that is based on a common pattern that is omnipresent in the image set, of common patterns extracted by the image-pair common pattern extraction unit
