Method for comparing two moving pictures and retrieval system using the method

摘要

A moving-picture comparison method allowing the degree of similarity to be precisely computed is disclosed. A database (104) stores a plurality of moving pictures and candidate feature data C_FD generated from each moving picture according to candidate timing information C_TC. After generating query feature data Q_FD from a query moving picture Q_MPD according to query timing information Q_TC, at least one of the candidate feature data and the query feature data is changed based on the query and candidate timing information so that one of the query and candidate feature data exists at a time position of the other. Thereafter, the query feature data and the candidate feature data are compared to compute the degree of similarity.
