  • Video super-resolution method, program, and device
    Patent number: 12639787
    Abstract: A video super-resolution device includes a down-sampler, video super-resolvers, and a selecting/averaging unit. The down-sampler divides an input low-resolution video into a plurality of frame rates. The video super-resolvers are video super-resolvers trained at different frame rates, and perform super-resolution of the low-resolution video. The selecting/averaging unit selects a video super-resolver according to the magnitude of an optical flow obtained as a result of video super-resolution. Specifically, in a case where the optical flow has a value smaller than 0.5 pixels, the selecting/averaging unit makes selection such as not adopting a result of video super-resolution at a high frame rate. Finally, the selecting/averaging unit obtains a mean value of the selected video super-resolution result, and outputs a final high-resolution video.
