Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and system for ordering songs from bullet screens based on face recognition. Background technique [0002] With the popularization of mobile terminals and the maturity of wireless network technology, the existing communication methods of voice calls and short messages can no longer meet people's needs, and video and voice chat services are increasingly favored by people.

Problems solved by technology

[0004] In the video communication method in the prior art, usually there is only real-scene avatar information captured by the cameras of both parties, and other pictures can be superimposed on the avatar information immediately, and the effect of superimposition is not good, and the superimposed pictures are fixed in advance, so the degree of flexibility is not high
