An articulated object region detection apparatus (100) includes: a subclass classification unit (105) which classifies trajectories into subclasses; a distance calculating unit (106) which calculates, for each of the subclasses, a point-to-point distance and a geodetic distance between the subclass and another subclass; and a region detection unit (107) which detects, as a region having an articulated motion, two subclasses to which trajectories corresponding to two regions connected via the same articulation and indicating the articulated motion belong, based on a temporal change in the point-to-point distance and a temporal change in the geodetic distance between two given subclasses. |
