Abstract
A network based platform uses face recognition, speech recognition, background change detection and key scene events to index multimedia communications. Before the multimedia communication begins, active participants register their speech and face models with a server. The process consists of creating a speech sample, capturing a sample image of the participant and storing the data in a database. The server provides an indexing function for the multimedia communication. During the multimedia communication, metadata including time stamping is retained along with the multimedia content. The time stamping information is used for synchronizing the multimedia elements. The multimedia communication is then processed through the server to identify the multimedia communication participants based on speaker and face recognition models. This allows the server to create an index table that becomes an index of the multimedia communication. In addition, through scene change detection and background recognition, certain backgrounds and key scene information can be used for indexing. Therefore, through this indexing apparatus and method, a specific participant can be recognized as speaking and the content that the participant discussed can also be used for indexing.
