Image generation method and device

Abstract

The embodiment of the invention provides an image generation method and device, relates to the technical field of image processing, and can solve the problems that an image obtained through processing according to the ERM principle is too smooth and lacks detail information. The image generation method comprises the steps: determining at least one detail orientation low-resolution feature map and at least one complementary orientation low-resolution feature map corresponding to a low-resolution image; determining a detail orientation super-resolution image corresponding to each detail orientation low-resolution feature map in the at least one detail orientation low-resolution feature map; determining a complementary directional super-resolution image corresponding to each complementary directional low-resolution feature map in the at least one complementary directional low-resolution feature map; and obtaining a super-resolution image corresponding to the low-resolution image according to the detail orientation super-resolution image and the complementary orientation super-resolution image. The image super-resolution method and device are applied to the image super-resolution process.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image generation method and device. Background technique [0002] Super-resolution technology (Super-Resolution) refers to recovering a high-resolution image from a low-resolution image or image sequence. Most current super-resolution processing methods for a single image use the principle of Empirical Risk Minimization (ERM). like figure 1 As shown, the X column represents the low-resolution image, and the Y column represents the image processed using the ERM principle. [0003] However, in the image obtained by using the ERM principle, the transition between pixels is often over-smooth, resulting in blurred images, over-smooth images, and lack of detail information. The overall effect looks quite different from the original image. Contents of the invention [0004] The embodiments of the present application provide an image generation method and ...
