Embodiment Construction

[0030] Artificial Intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is a comprehensive technique of computer science that attempts to understand the nature of intelligence and produce a new kind of intelligent machine that can respond in a similar way to human intelligence. Artificial intelligence is to study the design principles and implementation methods of various intelligent machines, so that the machines have the functions of perception, reasoning and decision-making.

[0031]Machine Learning (ML) is a multi-field interdisciplinary subject, involving probability theory, statistics, approximation theory, convex analysis, algorithm complexity theory and other disciplines. Specializes in the study of ho...

Abstract

The invention provides an image enhancement method and device. The image enhancement method comprises the steps of obtaining an original image; performing gray scale transformation on each pixel valueof the original image to obtain each target pixel value of the original image; and enhancing each target pixel value of the original image by using a pre-trained first image generator to obtain an enhanced image, so that the content, color and texture loss of the enhanced image is less than a predetermined threshold.

Description

technical field [0001] The present invention relates to the field of deep learning, in particular to an image enhancement method, device and storage medium based on deep learning. Background technique [0002] Image enhancement methods mainly include traditional image enhancement methods and image enhancement methods based on deep learning. In the traditional image enhancement based on histogram equalization, the contrast of noise can be increased, the contrast of useful signals can be reduced, and the gray level is reduced, so the image transition is unnatural. distortion. Image enhancement methods based on deep learning include image enhancement based on LightNet network. However, this method will cause image blockiness for noisy low-light images. In addition, the network requires image pairs that strictly correspond to high and low brightness during training, which are difficult to obtain and usually need to be manually generated. The present invention designs an imag...
