Embodiment Construction

[0088] It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0089] An embodiment of the present application provides an image resolution reduction and restoration method. In the first embodiment of the image resolution reduction and restoration method of the present application, refer to figure 1 , the image resolution reduction and restoration methods include:

[0090] Step A10, acquiring an image to be processed, and determining image gradient information corresponding to the image to be processed;

[0091] In this embodiment, it should be noted that the image gradient information is a matrix composed of gradient values ​​corresponding to each pixel in the image to be processed, and the image to be processed needs to be reduced in resolution to a higher resolution. A higher-resolution image of a low-resolution image, for example, assuming that the lower-resolution...

Abstract

The application discloses an image resolution reduction and restoration method and device and a readable storage medium. The image resolution reduction and restoration method comprises the following steps: r obtaining a to-be-processed image, determining image gradient information corresponding to the to-be-processed image; inputting the to-be-processed image into a preset image resolution reduction model; carrying out resolution reduction on the to-be-processed image to obtain an initial low resolution image, and storing the image gradient information in the initial low-resolution image to obtain a target low-resolution image, and inputting the target low-resolution image into a preset image restoration model to perform high-resolution restoration on the target low-resolution image basedon the image gradient information to obtain a target restored image. According to the invention, the technical problem of low restoration accuracy after image resolution reduction is solved.

Description

technical field [0001] The present application relates to the field of artificial intelligence, and in particular, to an image resolution reduction and restoration method, device, and readable storage medium. Background technique [0002] With the continuous development of computer software and artificial intelligence, the application of neural network models has become more and more extensive. At present, when high-resolution image transmission or storage is performed, due to the deep image bit depth of high-resolution images, the storage occupied The space is large, and the high-resolution image needs to be reduced to a low-resolution image with a lower image bit depth based on the neural network for storage, and then when the image is extracted, the low-resolution image is restored to a high-resolution image. However, when a low-resolution image is restored to a high-resolution image, the high-frequency information of the high-resolution image cannot be accurately restore...
