Video query system and method |
摘要 |
Search of video images in a database is enhanced by specification of at least one object and a background in stored frames and in queries of the database. Video information is stored in the database by means of representative frames that include at least one object and a background. A query of the database is executed by determining whether a representative frame in the database having at least one object and a background is similar to a search image having at least one object and a background.
