Abstract

The present invention relates to a system and a method for video instant communication. The system comprises a sending terminal (100) and a receiving terminal (200), the sending terminal (100) comprises a video receiving module, a face detection module, a face tracking module, a coding module, and a network communication module, and the coding module codes face information in a video sequence through a first coding algorithm, and codes inhuman face information through a second coding algorithm. The present invention applies the face recognition technology, the face detection technology, and the face tracking technology in the video instant communication, the face information and the inhuman face information adopt different coding algorithms, the information quantity is effectively reduced after being coded, and a band width is reduced; further, the inhuman face information can also be discarded, the operation quantity of the band width is further reduced, and the quality of the video communication is increased; the face information can also adopt the special algorithm, the face information is highlighted, and the user experience is increased.

Description

technical field [0001] The invention relates to the field of instant messaging (IM), in particular to a video instant messaging system and method, more specifically, to a video instant messaging system and method based on face detection and face tracking. Background technique [0002] With the popularization of instant messaging and the improvement of network bandwidth, more and more users start to use cameras for video chatting, video calling, video conferencing and so on. In video instant messaging, the two parties in the video communication usually pay more attention to the specific video content (for example, human face) of the image frame, and pay less attention to other information (such as the background). In the existing video instant messaging system, the sending end receives a video sequence through a video input device such as a camera, and uses a certain encoding algorithm to encode the image frame, that is, the sending end uses the same encoding algorithm to enc...
