Abstract

The invention provides an image super-resolution reconstruction method. The method comprises the following steps: obtaining a to-be-reconstructed low-resolution image; inputting the low-resolution image into a generation model in a trained generative adversarial network, and obtaining a super-resolution image corresponding to the low-resolution image output by the generation model, wherein the generation model has a preset first loss function, and the first loss function comprises a pixel difference loss function and a perception loss function. According to the invention, super-resolution reconstruction is carried out on the low-resolution image by using the trained generation model in the generative adversarial network; the loss function of the generation model comprises the pixel difference loss function and the perception loss function, so that the super-resolution image output by the trained generation model is infinitely close to a high-resolution image in detail, texture and semantics, and the human eye perception quality of the super-resolution image is improved. The invention further provides an image super-resolution reconstruction device.

Description

Technical field [0001] This application relates to the field of display technology, and in particular to a method and device for super-resolution reconstruction of an image. Background technique [0002] 8K TV is a TV with 7680×4320 ultra-high-definition resolution. With the development of 8K TV, the demand for high-resolution film sources in 8K TV has increased sharply. Because high-resolution film sources consist of multiple high-resolution images The demand for high-resolution images of 8K TVs has increased dramatically. [0003] At this stage, super-resolution reconstruction technology is usually used to obtain high-resolution images, that is, a given low-resolution image is restored to a corresponding high-resolution image through a specific algorithm. However, the high-resolution image obtained by the existing super-resolution reconstruction technology is still quite different from the real high-resolution image, resulting in poorer perception of the human eye.
