FIELD: information technology.SUBSTANCE: method involves extracting speeded up robust features (SURF) from reference video; storing SURF points from the reference video; determining trajectories of SURF points as spatial-temporal features of reference video based on the SURF points; storing the trajectories of SURF points; and generating indexes for the trajectories of SURF points.EFFECT: high accuracy of detecting video copies by constructing a trajectory of stable points of interest.24 cl, 7 dwg |
