Abstract

The invention discloses a video super-resolution reconstruction method. The video super-resolution reconstruction method comprises the following steps: acquiring a plurality of low-resolution trainingimage blocks which are continuous in time and a high-resolution training image block corresponding to at least one low-resolution training image block; training a convolutional neural network model by taking the plurality of low-resolution training image blocks as input data and taking the high-resolution training image blocks as truth value tags; and performing super-resolution reconstruction onthe low-resolution to-be-reconstructed video by using the trained convolutional neural network model. According to the method, the time-related characteristics of the video are fully considered in the training process of the model, so that unnecessary calculation overhead caused by frame-by-frame processing can be effectively avoided through subsequent super-resolution reconstruction.

Description

technical field [0001] The present application relates to the technical field of video processing, in particular to a video super-resolution reconstruction method. Background technique [0002] Super-resolution reconstruction refers to a technology that uses a computer to process a low-resolution image or video to obtain a high-resolution image or video. Super-resolution reconstruction can provide more detailed information than traditional interpolation methods, which can greatly improve the quality of images or videos. [0003] In related technologies, most super-resolution algorithms are aimed at a single image, that is, they are processed frame by frame. Specifically, the video super-resolution reconstruction algorithm usually intercepts the video as a frame-by-frame picture, performs super-resolution reconstruction on the entire picture, and then connects the results of each frame into a video, which will cause unnecessary computing overhead. [0004] In addition, for ...
