Abstract
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.
Claims15
A method for retrieving video sequences from a database that contains representative frames, each representative frame representing video information, the method comprising:
- receiving a search image and segmenting the search image into segments that include at least one object and a background;
- executing a query of the database by determining whether a representative frame in the database that has at least one object and a background that is similar to the search image;
- and
- returning a set of representative frames ranked in an order according to a degree of similarity to the search image.
A method of storing video information in a database, comprising:
- receiving a video sequence comprising a plurality of frames;
- providing a representative frame representing the video sequence;
- segmenting the representative frame into a plurality of segments that include at least one object and a background;
- constructing a frame data representation of the representative frame that includes respective data representations of the at least one object and the background;
- and
- storing the frame data representation in the database.
