Abstract

The embodiment of the invention discloses a figure replacing method in video live. A problem of how to replace the figure in the live can be solved. The method disclosed by the embodiment of the invention comprises the following steps: acquiring the current video frame image of a live target video in time; detecting whether a human face exists in the video frame image; if the human face exists in the video frame image, recognizing body silhouette corresponding to the human face at the position of the human face in the video frame image; determining a body coordinate position of the body silhouette in the video frame image; selecting a figure model matched with the body silhouette from a preset figure model set as a target model; replacing the body silhouette to the body coordinate position by use of the target model so as to synthesize a new video frame image; and outputting the new video frame image to the network to perform the live streaming. The embodiment of the invention further provides a figure replacing device in the video live and a recording and playing system.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a method and device for replacing characters in live video, and a recording and broadcasting system. Background technique [0002] With the popularization of the Internet, distance video teaching has become one of the important means of current education. At present, when conducting remote video teaching live lectures, the teacher usually takes the class in front of the camera as usual, uploads the video of the teacher's current lecture to the network in real time, and uploads the corresponding handouts of the teacher's current lecture to the network. Students can pass The image of the teacher during the lecture and the handouts of the current lecture can be seen remotely on the network, so that students feel as if the teacher is teaching face-to-face, thereby overcoming the limitation of distance and teaching in real time. [0003] However, in some application ...
