audiovisual information
ABSTRACT


As more and more audiovisual information becomes available from many sources around the world, many people would like to use this information for various purposes. This challenging situation led to the need for a solution that quickly and efficiently searches for and/or filters various types of multimedia material that’s interesting to the user.
For example, finding information by rich-spoken queries, hand-drawn images, and humming improves the user-friendliness of computer systems and finally addresses what most people have been expecting from computers. For professionals, a new generation of applications will enable high-quality information search and retrieval. For example, TV program producers can search with “laser-like precision” for occurrences of famous events or references to certain people, stored in thousands of hours of audiovisual records, in order to collect material for a program. This will reduce program production time and increase the quality of its content.
MPEG-7 is a multimedia content description standard that addresses how humans expect to interact with computer systems, since it develops rich descriptions that reflect those expectations.
