Abstract:
1. A human detection device which detects a human within a moving picture, said device comprising: a spatiotemporal volume generation unit configured to generate a three-dimensional spatiotemporal image in which frame images are arranged along a temporal axis, the frame images making up the moving picture in which a human has been filmed; a spatiotemporal fragment extraction unit configured to extract, from the generated three-dimensional spatiotemporal image, a real image spatiotemporal fragment which is an image appearing in a cut plane or cut fragment when the three-dimensional spatiotemporal image is cut; a spatiotemporal fragment output unit configured to generate and output, based on a human movement model which defines a characteristic of a movement of a human, a human body region movement spatiotemporal fragment, which is a spatiotemporal fragment obtained from the movement by the human movement model; a spatiotemporal fragment verification unit configured to verify a real image spatiotemporal fragment extracted by said spatiotemporal fragment extraction unit with a human body region movement model spatiotemporal fragment outputted by said spatiotemporal fragment output unit; an attribute output unit configured to output a human attribute which includes a presence/absence of a human in the moving picture, based on a verification result of said spatiotemporal fragment verification unit; and a display unit configured to display the presence/absence of a human based on the output of said attribute unit.
