Embodiment Construction

[0024] Hereinafter, the present invention will be discussed by describing preferred embodiments and by referring to the accompanying drawings. However, a person skilled in the art will realize other applications and modifications within the scope of the invention as defined in the appended independent claims.

[0025] When a streaming / archive server records (or archives) a videoconference, the people in the video are the most common and important element. Therefore, automatically determining the identity of anyone present at a meeting is a useful metric to include in metadata for meeting minutes, and would provide a useful avenue for user searches.

[0026] The present invention provides a novel streaming / archive server and novel method for making archived multimedia streams (eg videoconference and / or presentation data) queryable after archiving (recording) at the streaming / archive server. According to the present invention, one or more videoconferencing format encoded data s...

Abstract

The present disclosure discloses a method for identifying individuals in a multimedia stream originating from a video conferencing terminal or a Multipoint Control Unit, including executing a face detection process on the multimedia stream; defining subsets including facial images of one or more individuals, where the subsets are ranked according to a probability that their respective one or more individuals will appear in a video stream; comparing a detected face to the subsets in consecutive order starting with a most probable subset, until a match is found; and storing an identity of the detected face as searchable metadata in a content database in response to the detected face matching a facial image in one of the subsets.

Description

technical field [0001] The present invention relates to video conferencing, in particular to a face recognition method used in streaming / archiving equipment of a video conferencing device. Background technique [0002] For conducting meetings among participants not located in the same region, a variety of technology systems are available. These systems can include video conferencing, web conferencing or audio conferencing. [0003] The most realistic alternative to a real meeting is a high-end video conferencing system. A conventional videoconferencing system includes multiple endpoints (or terminals) that transmit real-time video, audio, and / or data streams over WAN, LAN, and / or circuit-switched networks. Endpoints include one or more monitors, cameras, microphones, and / or data capture devices and codecs that encode and decode output and input streams, respectively. In addition, a centralized source called a multipoint control unit (MCU) is required to link multiple endp...
