Problems solved by technology

In practical applications, due to the inability to ensure the accuracy of the optical flow between the original images of adjacent frames, the high frame rate video after the optical flow frame interpolation may appear broken edges of objects and other phenomena that affect the user's viewing experience

Abstract

The present disclosure relates to a method and device for improving the effect of frame insertion. The method includes: based on the optical flow frame interpolation method, determining an interpolation frame image between two adjacent frames of original images; judging whether the interpolation frame quality of the interpolation frame image meets the standard; When the quality is not up to standard, update the interpolated frame image. The disclosure can improve the frame interpolation quality of the interpolated frame image obtained based on the optical flow frame interpolation method, and effectively improve the viewing experience of the user on the high frame rate video obtained after the frame interpolation.

Description

technical field [0001] The present disclosure relates to the field of video processing, and in particular to a method and device for improving the effect of frame insertion. Background technique [0002] Video frame rate upscaling is a video post-processing method that converts low frame rate video into high frame rate video. It uses the temporal correlation between the original images of adjacent frames to determine the interpolated frame image, and then inserts the interpolated frame image into the Between the original images of adjacent frames to achieve the purpose of increasing the frame rate. For example, increase the video frame rate from 30fps (Frames per Second, frame per second) to 60fps. The higher the video frame rate, the smoother the motion in the video screen, and the better the user viewing experience. [0003] At present, the commonly used video frame rate improvement method is the optical flow interpolation method based on optical flow, which calculates t...
