Abstract

The embodiment of the invention discloses a video frame insertion method and device, equipment and a medium. The method comprises the following steps: acquiring two adjacent frames in a target video; respectively performing down-sampling processing on a first frame and a second frame in the two adjacent frames to obtain a first down-sampling frame and a second down-sampling frame; determining a first down-sampling optical flow diagram, a second down-sampling optical flow diagram and down-sampling correction information based on a preset optical flow correction model; performing up-sampling processing on the first down-sampling optical flow diagram, the second down-sampling optical flow diagram and the down-sampling correction information to obtain a first up-sampling optical flow diagram, a second up-sampling optical flow diagram and up-sampling correction information; and determining an intermediate frame between two adjacent frames according to the first frame, the second frame, the first up-sampling optical flow diagram, the second up-sampling optical flow diagram and the up-sampling correction information on the basis of a preset conversion integration model, and determining a target insertion frame corresponding to the two adjacent frames on the basis of the intermediate frame, thereby improving the video frame insertion efficiency on the premise of ensuring the frame insertion effect.

Description

technical field [0001] The embodiments of the present disclosure relate to computer technologies, and in particular, to a video frame insertion method, apparatus, device, and medium. Background technique [0002] With the rapid development of computer technology, the frame rate and fluency of the video can be improved by performing frame insertion operations on the video, so as to meet the user's high-quality requirements for the video. At present, video frame interpolation is usually performed based on optical flow, and an interpolated video frame between two adjacent frames is determined. However, in the existing frame interpolation method, the frame interpolation operation is directly performed on the video frames of the original resolution, which often requires a long frame interpolation time, thereby reducing the video frame interpolation efficiency. SUMMARY OF THE INVENTION [0003] Embodiments of the present disclosure provide a video frame insertion method, appara...
