Abstract

The invention discloses an image super-resolution reconstruction method. The method comprises the steps that a low-resolution feature space and a high-resolution feature space are constructed into multiple low-resolution feature subspaces and high-resolution feature subspaces arranged in pairs; a linear mapping relation is established between the low-resolution feature subspaces and the high-resolution feature subspaces arranged in pairs; and a low-resolution reconstructed image is reconstructed into a high-resolution reconstructed image according to the linear mapping relation. By the adoption of the image super-resolution reconstruction method, the high-quality high-resolution image can be obtained rapidly.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image super-resolution reconstruction method. Background technique [0002] When obtaining high-resolution images, improving the physical resolution of the imaging system is the most direct and effective means. However, upgrading the physical resolution of the imaging system requires sophisticated manufacturing techniques and high-cost components. Therefore, in most cases, image processing techniques such as image super-resolution reconstruction are used to convert low-resolution images into high-resolution images. [0003] However, in the existing image super-resolution reconstruction technologies, some technologies guarantee high-quality high-resolution images, but there are problems of complex calculation, time-consuming and memory consumption; some technologies are simple and fast in calculation, but cannot guarantee high-quality images. image.
