Problems solved by technology

However, most of the existing image repair methods generate images from the perspective of mathematics and physics, without considering the semantic information of the image, so they can only repair images with small damaged areas; repair images with large damaged areas When , there are problems that the restoration effect is poor, semantic information may be lost during the restoration process, and it is difficult to repair the details of irregular areas and high-frequency images.

Abstract

The invention discloses an image restoration method and system based on a progressive learning strategy, a storage medium and terminal device, and the method comprises the steps: inputting a to-be-restored image into a rough generation model, so as to obtain a rough generation result; extracting a feature map of the rough generation result to obtain a foreground feature map; and matching the foreground feature map with a background feature map, and reconstructing the foreground feature map by using the obtained background sample block with the highest matching degree with the foreground feature map. According to the method, when the large-area damaged area in the image is generated, the semantic integrity of the image is kept, clear details are generated, a good restoration effect is achieved on the image with the high structure, and therefore the image restoration experience of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image restoration method, system, computer-readable storage medium and terminal equipment based on a progressive learning strategy. Background technique [0002] Image inpainting is an important part of image restoration, which refers to filling information in the information-deficient areas on the image, and restoring the truth to the greatest extent, so that the restored image is visually and semantically authentic. Its purpose is to use the existing information of the image to restore the missing information. However, most of the existing image repair methods generate images from the perspective of mathematics and physics, without considering the semantic information of the image, so they can only repair images with small damaged areas; repair images with large damaged areas When , there are problems that the restoration effect is poor, semantic informatio...
