Video matching device, method, and program |
摘要 |
A matched state detection unit (33) of a video matching device (100) detects a reference video frame, of the respective video frames of a reference video (1) and degraded video (2B), which is in a matched state in which it is spatially and temporally matched with each degraded video frame. A matching degree derivation unit (34) controls a degradation amount derivation unit (40) to acquire the first degradation amount indicating the degradation amount between a reference video frame and a degraded video frame in the matched state and the second degradation amount indicating the degradation amount between a reference video frame and a degraded video frame in a state shifted from the matched state by a predetermined number of pixels and calculate a matching degree on the basis of the ratio between the first degradation amount and the second degradation amount. A matching information output unit (35) outputs the matching degree between the reference video and the degraded video after matching.
