Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] Image restoration is a very important research topic in image processing. Image restoration refers to restoring the damaged image to its original similar state through certain technical means. At present, image inpainting methods have been widely used in fields such as old image restoration, photo beautification, background figure removal, and 3D photography.

[0027] In related technologies, image restoration methods include traditional image restoration algorithms and image restoration methods based on deep learning. Among them, the traditional image restoration algorithm uses algorithms such as expansion to fill, and uses the pixels in the adjacent area to fil...

Abstract

The invention discloses a training method and device of an image restoration model, computer equipment and a storage medium. The training method o comprises the steps of obtaining a mask image corresponding to a sample image; extracting an edge image of the sample image as a first edge image; based on a pre-trained edge completion model, performing edge completion on the first edge image to obtain a completed edge image as a second edge image; based on the mask image, acquiring a repair mask image and a context mask image corresponding to the sample image, wherein the repair mask image is used for indicating a to-be-repaired area in the sample image, and the context mask image is used for indicating a known image area when the to-be-repaired area is repaired; and training the initial model based on the sample image, the repair mask image, the context mask image and the second edge image to obtain a trained image repair model. The image restoration effect of the image restoration model can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, to a training method, device, computer equipment and storage medium for an image restoration model. Background technique [0002] With the rapid advancement of technology and living standards, electronic devices (such as smart phones, tablet computers, etc.) are widely used by people, and the shooting functions of electronic devices are becoming stronger and stronger. High quality images. However, in the process of image shooting, transmission, processing, and storage, due to various factors, there may be missing, cracks, etc. in the image. Therefore, there have been methods for repairing these defective images, but the image restoration effect of the current image restoration methods is not good. Contents of the invention [0003] In view of the above problems, the present application proposes a training method, device, computer equipment and storage...
