Abstract

The invention provides an efficient video enhancement method and a device for a mobile terminal, and a storage medium. According to the method, an optimized CNN denoising model and an optimized CNN super-resolution model are adopted; an image is split into a plurality of sub-images to serve as input of a CNN denoising model; the CNN denoising model and the CNN super-resolution model only process the Y-channel information of the image; the U and V channel information of the large-size image is obtained by using a simple super-resolution method, the complexity of the model is reduced through theoptimization method, and the improvement of the overall enhancement effect is achieved by effectively combining the denoising model and the super-resolution model.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an efficient video enhancement method applied to a mobile terminal. Background technique [0002] With the development of video technology and network technology, high-quality video has become an important demand of people. In reality, there are still many low-quality video resources, including old movies shot with low-quality equipment, some UGC (User Generated Content, User Generated Content) videos shot by non-professionals, etc. The low-quality problems of videos include low resolution , large compression noise, large background noise, etc. [0003] Video enhancement aims to convert the existing low-quality video into high-quality video through a series of enhancement techniques. Common video enhancement techniques include super-resolution, denoising, etc. Super-resolution is a classic problem in the field of computer vision, which aims to restore high-resolution images (or...
