Abstract

The invention provides an image reconstruction method, a terminal and a computer readable storage medium. The method includes the following steps: extracting a plurality of local image blocks in a to-be-reconstructed image; calculating the hash key value of each local image block according to gradient feature information of each local image block in the to-be-reconstructed image, wherein there is a mapping relationship between the hash key values and the gradient feature information; calculating the pixel value of a target image block according to the hash key values, wherein the number of pixels in the target image block is N<2> times the number of pixels in each local image block, N>=2, and N is a positive integer; and reconstructing a super-resolution image according to the calculated pixel value of each local image block, wherein the resolution of the super-resolution image is N times the resolution of the to-be-reconstructed image. The method of the invention reduces the computation complexity and improves the operation speed. Moreover, the method has high processing speed, and the reconstructed high-resolution image is of high clarity and has good edge features.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image reconstruction method, a terminal and a computer-readable storage medium. Background technique [0002] Image super-resolution reconstruction technology is widely used in the fields of medical image analysis, remote sensing, and computer vision. It is an effective way to deal with the problem of insufficient image clarity and image resolution degradation after network transmission compression. This technology is to obtain a high-resolution (High-Resolution, HR) image from a single low-resolution (Low-Resolution, LR) image through a certain operation. [0003] At present, single image super-resolution reconstruction methods are mainly divided into two categories: [0004] 1. Based on the interpolation method, this method uses a variety of interpolation methods, including bilinear interpolation algorithm, bicubic interpolation algorithm, and Hermitian int...
