A moving object detection apparatus (100) includes: an image input unit (101) which receives a plurality of pictures included in video; a trajectory calculating unit (102) which calculates a plurality of trajectories from the pictures; a subclass classification unit (103) which classifies the trajectories into a plurality of subclasses; an inter-subclass approximate geodetic distance calculating unit (104) which calculates, for each of the subclasses, an inter-subclass approximate geodetic distance representing similarity between the subclass and another subclass, using an inter-subclass distance that is a distance including a minimum value of a linear distance between each of trajectories belonging to the subclass and one of trajectories belonging to the other subclass; and a segmentation unit (105) which performs segmentation by determining, based on the calculated inter-subclass approximate geodetic distance, a set of subclasses including similar trajectories as one class. |
