Scene change detection in an MPEG-compressed video sequence

An algorithm is proposed for the detection of abrupt scene change and special editing effects such as dissolve in a compressed MPEG/MPEG-2 bitstream with minimal decoding of the bitstream. Scene changes are easily detected with DCT DC coefficients and motion vectors. By performing minimal decoding on the compressed bitstream, the processing speed for searching a video database of compressed image sequences can be dramatically improved. In addition, the algorithm may also be applied in video scene browsing and video indexing as well.
