Computer-readable storage medium, video replacement synthesis method and system

Abstract

The embodiment of the present invention provides a computer-readable storage medium, a video replacement and synthesis method and system, the method includes acquiring the video object's facial video to be replaced and the facial video of the replacement material; acquiring the video mouth shape of the facial video to be replaced Change the unrelated point, facial displacement distance and facial rotation angle, and obtain the replacement video of the replacement material facial video. The mouth shape change unrelated point, facial displacement distance and facial rotation angle; perform head motion elimination processing on the replacement material facial video, and Perform mouth muscle group mask processing to obtain the replacement material mouth muscle group video; make the replacement material mouth muscle group video cover the mouth muscle group in the face video to be replaced, and according to the face displacement of the video to be replaced and the face of the video to be replaced Move and rotate the angle to rotate the video of the mouth muscle group of the replacement material to obtain a composite video. By adopting the system, the method and the storage medium, the requirements on the consistency of the video objects in the synthesized video can be reduced.

Description

Technical field [0001] The embodiment of the invention relates to the field of video synthesis, in particular to a computer readable storage medium, a video substitution synthesis method and system. technical background [0002] In the process of teaching, the use of recorded video to explain the course can greatly liberate the workload of lecturers. However, due to the different lecturers, the recorded video can't be changed according to the different lecturers in the interactive session, which will greatly affect the feelings of lecturers. [0003] In order to improve the above situation, at this stage, the interactive videos of the participants in this course are mainly formed by splicing and replacing the videos of the interactive links. To ensure the authenticity of the videos, it is required that the scenes shot by the replacement videos of the interactive links and the whole videos, as well as the makeup and costumes of the teachers, should be consistent. For training inst...

[0002] In the teaching process, the use of recorded video to explain the course can greatly relieve the workload of the lecturer. However, due to the difference of the lecturers, in the interactive link, the recorded video cannot be changed according to the different lecturers, which will greatly affect the lecturers. feeling

[0003] In order to improve the above situation, at this stage, it is mainly through editing and replacing the part of the video in the interactive part to form an interactive video corresponding to the participants of this course. In order to ensure the authenticity of the video, it is required that the replacement video of the interactive part and the overall video The shooting scene and the makeup and clothing of the teachers are consistent. For training institutions, the video recorded for the same teacher may be applied to many classes, that is, there will be multiple videos corresponding to the same overall video. Combining the replacement video with it means that multiple replacement videos will be recorded, and the consistency requirements for video objects also increase the difficulty of shooting
