Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0044] 1. GAN

[0045] Generative adversarial networks have achieved great success in generating realistic images. It mainly consists of two parts, a generator (Gen) and a discriminator (Disc). The loss function is optimized based on max-min game theory to achieve a balance between Gen and Disc, and the training process consists of two steps. Disc is trained to distinguish between synthetic images generated by Gen and real images sampled from real image datasets. Gen, on the other hand, is trained to generate fake images that can be confused with real ones. The goal of training is...

Abstract

The invention relates to an unsupervised image restoration method for resisting network migration learning based on mask generation, comprising the following steps: step S101, obtaining an image to berepaired and setting mask parameters;step 102, utilize a mask to generate an antagonistic network for repairing that image to be repaired; The mask generation countermeasure network comprises a self-encoder and a discriminator. The training process of the mask generation countermeasure network comprises adding a mask layer after the output of the self-encoder, and the mask layer is used as the first layer of the discriminator to realize the training of the self-encoder and the discriminator. Compared with the prior art, the invention has the advantages of high accuracy and high efficiency.

Description

technical field [0001] The invention relates to an image restoration method based on artificial intelligence, in particular to an unsupervised image restoration method based on mask generation confrontation network migration learning. Background technique [0002] In practical applications, images sometimes have broken or blurred areas that need to be repaired. The goal of image restoration is to reconstruct the missing or corrupted parts of an image. Over the past few years, image inpainting has been intensively studied, focusing on reconstructing retouched or incomplete parts of an image. These studies usually employ autoencoders as the basic structure and incorporate other tricks, such as adversarial learning, to improve performance. According to whether the full image is known or not, previous works can be mainly divided into two categories. [0003] The first category is supervised image inpainting. Supervised image inpainting methods focus on problems known from th...
