Abstract

The present application relates to an image generation method and apparatus based on video frame interpolation, and a computer device. The method comprises: acquiring two video frame images, and on the basis of the displacement of pixel points in the two video frame images, determining first optical flow information between the two video frame images (202); on the basis of the two video frame images and the first optical flow information, predicting an intermediate frame image between the two video frame images to obtain a predicted intermediate frame image (204); for each of the two video frame images, on the basis of the video frame image and the displacement of pixel points in the predicted intermediate frame image, determining second optical flow information between the video frame image and the predicted intermediate frame image (206); for each first pixel point in the predicted intermediate frame image, acquiring, from the second optical flow information, a position offset corresponding to the first pixel point, and on the basis of the position offset, selecting an image block corresponding to the first pixel point from the video frame image (208); on the basis of an image block corresponding to each first pixel point in the predicted intermediate frame image, updating a pixel value at each first pixel point in the predicted intermediate frame image to obtain an updated intermediate frame image corresponding to the video frame image (210); and fusing the updated intermediate frame images corresponding to the two video frame images respectively to obtain a fused intermediate frame image (212).
