Abstract

The invention provides a super-resolution image reconstruction method and device based on depth learning, including the following steps: according to the image set and the magnification of the target,a training set corresponding to the high-resolution image and the low-resolution image is established, based on the training set and the pre-constructed multi-scale network model, network training isconducted, so that the model parameter are obtained, wherein the multi-scale network model comprises a plurality of feature extraction networks and a composite network, multiple feature extraction networks are used to extract features from images, and combined networks are used to combine multiple sets of features extracted from multiple feature extraction networks; using the trained multi-scalenetwork model, the input low-resolution images are reconstructed to obtain high-resolution images. A better reconstruction effect can be obtained by extracting features from images through multiple feature extraction networks with different network depths and combining multiple features.

Description

technical field

[0001] The present invention relates to the technical field of image processing, in particular to a super-resolution image reconstruction method and device based on deep learning. Background technique

[0002] Super-resolution (Super-Resolution) is to improve the resolution of the original image through hardware or software. The process of obtaining a high-resolution image through a series of low-resolution images is super-resolution reconstruction. Super-resolution has broad application prospects in the fields of video compression and transmission, medical image-aided diagnosis, security monitoring, and satellite imaging.

[0003] Super-resolution mainly has the following two evaluation criteria: (1) the reconstruction effect of the image, the goal of reconstruction is to restore the high-frequency information of the image, improve the quality of the image, and improve the visual effect of the reconstructed image as much as possible; (2) the image quality T...
