Title:
VIDEO FRAME INSERTION METHOD AND APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/217653
Kind Code:
A1
Abstract:
The present invention relates to the technical field of image processing, and provides a video frame insertion method and apparatus, and a computer-readable storage medium. The method comprises: inputting at least two image frames into a video frame insertion model to obtain at least one frame insertion image frame, obtaining a reference model by using a first loss training initial model, duplicating the reference model to obtain three reference models that share parameters, and selecting different target sample images according to a preset rule so as to train a first reference model and a second reference model to obtain a first frame insertion result and a second frame insertion result; according to the preset rule, selecting a third target sample image from among the first frame insertion result and the second frame insertion result so as to train a third reference model to obtain a frame insertion result, obtaining the total loss of the first reference model according to the frame insertion results and sample images, adjusting the parameters of the reference model according to the total loss, and using a parameter model that has undergone a predetermined number of iterations as a video frame insertion model. The technical solutions of the embodiments improve the frame insertion effect and save computing resources.
