Abstract

The invention provides a method for establishing an index for multimedia. The method comprises the following steps: searching names found out in speech or a text relevant to the multimedia on an image searching engine and establishing a corresponding face database for the names according to the search result; respectively extracting the characteristics for each face in the face database and videoframes of a video or a to-be-detected face in a picture; respectively carrying out characteristic matching on the to-be-detected face and each face in the face database and acquiring whether the to-be-detected face is matched with the name represented by the face database according to the matching result; and taking the matched name as the multimedia index. The method does not require human interference and prior data labeling and has ideal expansibility; and the method can solve the problem of frequent small sample volume in face matching operation, name a small number of faces in news reports conveniently and effectively and establish a relevant index.

Description

technical field [0001] The invention relates to a method for creating an index for multimedia, in particular how to use a search engine to realize the creation of a multimedia index.
