Problems solved by technology

[0003] When restoring the clarity of images and videos, models are usually used to process low-resolution images and videos to obtain high-definition images and videos, but Existing models can only deal with images of one definition (magnification), and it is impossible to restore the definition of ima

Abstract

The invention relates to the technical field of computers, and provides a model training and image processing method and device, a computer readable medium and electronic equipment, and the method comprises the steps: obtaining a plurality of original images with the first definition; processing the original image according to the random reduction factor and the random noise intensity generated bythe random number generator to obtain a training image corresponding to the original image, the training image having a second definition which is lower than the first definition; and training a definition recovery model according to the original image and the corresponding training image. The image processing method is used for processing the to-be-processed image based on the model trained by the training method to generate a target image. On one hand, images with different definition and resolutions can be processed through one model, and the definition and the resolution are improved; onthe other hand, the user experience can be further improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a model training and image processing method, a model training and image processing device, a computer-readable storage medium and electronic equipment. Background technique [0002] With the development of science and technology, in order to improve the perception, people have higher and higher requirements for the picture quality of video and images. Taking video as an example, the resolution is usually set with SD, HD, and UHD options. High-quality picture quality is getting more and more attention. In electronic imaging applications, images with higher resolution are more desirable. An image with higher resolution has a greater pixel density and therefore shows more detail than a lower resolution image of the same scene. Higher-resolution images have many applications including, for example, medical imaging, satellite imaging, computer vision, video surveillance, facial recognition...
