- Abstract
To efficiently detect near-duplicate Web videos and deal with the problems of poor robustness and bad similarity measurement in the exiting algorithms based on ordinal measures, this paper proposed a method based on core area ordinal measures and the transformation distance. After analyzing Web near-duplicates, it selected the comparatively invariant area of copy video to extract ordinal measure fingerprints. Then it used the minimum cost of the transformation to measure the distance between the ordinal measures, and designed the effective algorithm for fingerprint matching. Finally, the proposed method used the simplified longest same sub-sequences algorithm to match the sequences of features and detect the copy clips. Experimental results based on real network and MUSCLE-VCD-2007 datasets show good robustness of core area ordinal measures and excellent performance of copy detection.
