Abstract

The invention provides an image processing method, an image processing device, a terminal device and a readable storage medium. The method comprises the steps of obtaining a to-be-processed image to be subjected to super-resolution reconstruction; carrying out image segmentation on the to-be-processed image to obtain a first image containing a target object and a second image containing other image areas, and setting the pixel values of other pixel points in the first image to be zero except the target object; inputting the first image into a first neural network model, obtaining a corrected first image after super-resolution reconstruction, and performing super-resolution reconstruction on the second image by using a preset algorithm to obtain a corrected second image, the high-frequencyinformation energy contained in the corrected first image being greater than a first threshold, and the duration of processing the second image by using the preset algorithm being less than a second threshold; and fusing the corrected first image and the corrected second image to obtain a processed image. According to the application, the super-resolution reconstruction effect and the consumed time of the super-resolution reconstruction can be considered at the same time.

Description

technical field [0001] The present application belongs to the technical field of computers, and in particular relates to an image processing method, an image processing device, a terminal device, and a computer-readable storage medium. Background technique [0002] At present, the trained neural network model is often used for super-resolution reconstruction of images. However, under normal circumstances, when the trained neural network model is used for super-resolution reconstruction of images, the neural network model with better reconstruction effect is often It takes a long time. [0003] Therefore, how to reduce the time spent on super-resolution reconstruction under the premise of ensuring a good super-resolution reconstruction effect is an urgent technical problem to be solved at present. Contents of the invention [0004] The present application provides an image processing method, an image processing device, a terminal device, and a computer-readable storage med...
