The invention discloses a method for transmitting a human face video. The method comprises the following steps of: S1, acquiring a video, and obtaining a human face model by training the video; S2, sharing the human face model between a transmission end and a receiving end; S3, carrying out human face positioning and parameter fitting on the video by using the human face model so as to obtain model parameters; S4, optimizing the model parameters according to transmission rate limit, so as to enable the model parameters to meet the requirements on the limit on the transmission rate in the transmission process, and transmitting the optimized model parameters to the receiving end; S5, carrying out reduction on the model parameters transmitted by the transmission end after the receiving end receives the model parameters transmitted by the transmitting end; and S6, carrying out human face image reconstruction by using the reduced model parameters and the shared human face model through the receiving end. By utilizing the method for transmitting the human face video, the data quantity desired in transmission is greatly reduced, parameter errors are minimized while the characteristics of a transmission channel are adapted, the redundancy caused by the fact that the parameters are transmitted in each frame is avoided, and the velocity in data transmission is increased.
Description
technical field [0001] The invention relates to the field of video transmission, in particular to a face video transmission method. Background technique [0002] Since the 1990s, technologies ranging from digital television broadcasting to wireless multimedia communication have been widely used in countries all over the world. The popularization of the Internet has freed multimedia communication from the limitations of television: the emergence of video chat software such as Skype and Google Talk allows people to conduct multimedia communication such as video calls and remote conferences through computers. Nowadays, with the rapid development of smart phones, applications such as Facetime and Tango on mobile terminals make multimedia communication popular on mobile networks, and more and more users expect convenient, fast and ubiquitous multimedia communication services. How to greatly reduce the encoding method of the video data volume is a key technology to ensure the sus...
