Problems solved by technology

[0004] In the existing technology, the quality enhancement and super-resolution reconstruction networks are trained and used independently. When the two are used in combination, the total performance is much lower than the sum of the two independent performances, and the potential performance of the two cannot be fully exploited.

Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only part of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0038] In the prior art, image resolution enhancement processing and quality enhancement processing are realized through two independent models. When the two are used in combination, the total performance is far lower than the sum of the performances of the two independently used, and cannot fully release model potential. The present application provides an image reconstruction method capable of implementing resolution enhancement processing and quality enhancement processing. The m...

Abstract

The invention provides an image reconstruction method, a coding and decoding method and a related device, the image reconstruction method is carried out based on an image reconstruction model, the image reconstruction model comprises a feature processing layer, a super-division processing layer and an enhancement processing layer, and the method comprises the following steps: carrying out feature extraction on an input image by using the feature processing layer to obtain a feature image; processing the feature image by using a super-resolution processing layer to obtain a first output image; processing the feature image by using an enhancement processing layer to obtain a second output image; wherein the resolution of the first output image is greater than that of the input image; the objective quality of the second output image is greater than the objective quality of the input image. The image super-division and enhancement share a feature processing layer, so that the computing performance is improved, and the computing resource overhead is reduced.

Description

technical field [0001] The present invention relates to the technical field of video encoding and decoding, in particular to an image reconstruction, encoding and decoding method, and a related device. Background technique [0002] The amount of video image data is relatively large, and it is usually necessary to compress the video pixel data (RGB, YUV, etc.). The compressed data is called a video code stream. The video code stream is transmitted to the client through a wired or wireless network, and then decoded and viewed. . The entire video encoding process includes processes such as block division, prediction, transformation, quantization, and encoding. In order to compress video data more effectively, high-resolution images are down-sampled to low-resolution images in codec, and when high-resolution images are required, up-sampling is used to enlarge or super-resolution technology is used for reconstruction. [0003] Super-resolution reconstruction technology not only...
