Embodiment
[0078] This embodiment provides a video super-resolution method based on multi-frame attention mechanism progressive fusion, such as figure 1 shown, including the following steps:
[0079] S1. Video decoding: use the ffmpeg tool to extract frames from the video data set and save them as pictures to generate a training set.
[0080] Here, the video dataset contains high-resolution videos and low-resolution videos with the same video content. High-resolution videos refer to videos that reach the target resolution, and low-resolution videos refer to videos that are lower than the target resolution.
[0081] All the frames of the high and low resolution videos are reserved, and each low resolution video image has a corresponding high resolution video image to form the initial training set; the initial training set has N pairs of images: {(x 1L ,x 1H ),(x 2L ,x 2H ),…,(x NL ,x NH)}, where x NL Represents the low-resolution video image in the Nth pair of images; x NH Represe...
