VIDEO MATCHING DEVICE, METHOD, AND PROGRAM

摘要

A video matching device (100) includes: matching state detection means (33) for detecting a reference video frame in a spatially and temporally matched state for each degraded video frame among each video frame of a reference video (1) and a degraded video (2B); matching degree decision means (34) for controlling a degraded amount decision unit (40) so as to acquire a first degraded amount indicating a degraded amount between a reference video frame and a degraded video frame in a matched state and a second degraded amount indicated a degraded amount between the reference video frame and the degraded video frame in a state shifted from the matched state by a predetermined number of pixels and calculating the matching degree according to the degraded amount ratio of the first degraded amount against the second degraded amount; and matching information output means (35) for outputting the reference video and degraded video after matching and the matching degree.
