An algorithm is proposed for the detection of abrupt scene change and special editing effects such as dis- solve 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.
要通顺点的

算法为突然的场面变动的侦查提议，并且特别编辑作用例如dis-在与最小解码的一压缩的MPEG/MPEG-2 bitstream解决bitstream。 场面变动容易地查出与DCT DC系数和行动传染媒介。 通过执行最小解码在压缩的bitstream，可以巨大改进搜寻的压缩的图象序列录影数据库处理速度。 另外，算法在录影场面浏览和录影索引也许也被运用。
