Problems solved by technology

However, on the one hand, when inpainting an image, it is usually difficult to find a general inpainting law due to the complex texture structure and uncertain noise of the missing area and background, so it is very difficult to directly build a mathematical model for inpainting
On the other hand, since image inpainting is an ill-conditioned inverse problem, it reconstructs the information of the missing area through the learning, understanding and inference of the image perception process according to the acquired part of the image information. However, the reconstruction result is not unique. Finding the optimal inpainting result is also a challenging problem

Embodiment Construction

[0020] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0021] The present invention proposes a progressive image restoration method based on a generative adversarial neural network, using a generative network with a short-circuited "encoder-decoder" structure to generate a forged image, and judging the input through a global discriminator and a local discriminant network Whether the image is real data. In the present invention, the whole restoration process is divided into 4 sub-s...

Abstract

The invention discloses an image restoration method based on a generative adversarial neural network, and the method employs four parts: a generative network, a global discrimination network, a localdiscrimination network, and an LSTM neural network. And the two discriminators are mainly used for ensuring that the repaired missing area can keep consistent with the surrounding area. The LSTM neural network is mainly used for repairing damaged images by stages. The algorithm comprises a data preprocessing module, a model training module and an image restoration module, and is mainly used for performing a semantic restoration task on a large-area missing image so as to reconstruct a complete and vivid image conforming to human eye senses.

Description

technical field [0001] The invention relates to an image restoration method based on a generative confrontational neural network, which belongs to the field of image semantic restoration. Background technique [0002] As an important information carrier of the objective world, images are the main source and means for human beings to obtain and identify external information. High-quality images can bring people richer information and content, and even give people a beautiful viewing experience. However, in real life, it is not guaranteed that all acquired images are of high quality. In the process of image collection, transmission, storage, etc., after some image processing operations, image information will often be lost. decline in quality. For example, in the process of image transmission, due to channel bandwidth limitation or channel damage, information may be lost in the transmitted image. In order to improve the image quality and ensure the effectiveness of informat...
