Abstract

The invention discloses a video synthesis method. The video synthesis method comprises: acquiring K frames of source image information of a first to-be-synthesized video, each frame of image information comprises a source image and a source action key point, the source image and the source action key point have a corresponding relation, multi-frame target image information of a second to-be-synthesized video is acquired, and each frame of target image information comprises a target action key point; obtaining a first output image corresponding to the K frames of source image information and the first target action key point through a video synthesis model, wherein the video synthesis model is used for carrying out fusion processing on the source image, the source action key point and the target action key point; and generating a composite video according to the action reference sequence and the first output image. The invention further discloses a model processing method and device. According to the method, the output image corresponding to the action sequence can be generated by utilizing the multi-frame source image information, so that the information relevance between continuous frames is fully considered, and the time domain continuity of the synthesized video is enhanced.

Description

technical field [0001] The present application relates to the field of artificial intelligence, in particular to a video synthesis method, a model training method and related devices. Background technique [0002] With the diversity of media forms, a strategy for migrating the actions of characters in different videos is proposed. For two videos, one is the target person whose action is to be synthesized, and the other is the source person of the transferred action. Motion transfer between characters through a pixel-based end-to-end process. Video motion transfer can enable untrained amateurs to perform dance moves like professional ballerinas and dance like pop stars. [0003] At present, in the video action transfer method, the commonly used processing method is to first provide two videos, one video includes the transfer object, and the other video includes the action reference sequence, and then performs a single-step operation on each frame of the video according to t...
