Paper Abstract

In this paper, we propose an efficient shot boundary detection algorithm for direct processing of MPEG-2 video sequences. The proposed algorithm utilizes the hierarchical structure of the compressed bitstreams and characteristics of the coded parameters, for example, picture coding type and macroblock coding mode, thus greatly reducing computational requirement compared to pixel domain processing with full decompression. Occurrence of a shot boundary is checked first in a sub-GOP level, and if the result is affirmative it is checked again in each picture. And, to solve selection of appropriate threshold values, we use the hypothesis test with statistical characteristics of the coded parameters, for example, the ratio of intra-coded macroblocks to inter-coded macroblocks, the ratio of the backward macroblocks to bi-directional macroblocks, and the ratio of forward macroblocks to bi-direction macroblocks.
