ummary of methods for video classification and indexing is given in this paper. An adaptive algorithm is proposed and a method using color trade-off between object and background is also suggested to video indexing. The time-cost for adaptive algouth is dependent on the amount of change between cosecutine frames. For most of neighbor frames
the number of local regions used for classification is very small. Experimental results show that the proposed methods for video classification and indexing are fast and accurate.
