Abstract:
1. A method for comparing a query video and a target video, the method including: partitioning frames of the query video and frames of the target video into blocks; calculating the mean intensity values for the blocks; producing a plurality of query time series for the query video, the query time series representing temporal variation in mean intensity value for blocks from the same location in different frames of the query video; producing a plurality of target time series for the target video, the target time series representing temporal variation in mean intensity value for blocks from the same location in different frames of the target video; determining if alignment exists between the query video and the target video using the query time series and the target time series; segmenting the query time series and the target time series into a respective set of discrete linear segments; and performing local sequence alignment of those linear segments.
