Embodiment Construction

[0021] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0022] With the development of information technology and Internet technology, users have put forward higher requirements for the clarity of videos. Super-resolution reconstruction can reconstruct low-resolution images in videos into high-resolution video images through artificial intelligence deep learning. Make the video clearer and bring better video experience to users on the mobile terminal. Due to various objective limitations in practical applications, noise usually exists in video. For example, noise may be caused by limitations such as insufficient camera capture capabilities or video compression during transmission. In the process of super-resolution reconstr...

Abstract

The invention discloses an image processing method and device, electronic equipment and a storage medium. The invention discloses an image processing method, and the method comprises the steps of obtaining a to-be-processed video frame sequence, and enabling each video frame in the to-be-processed video frame sequence to serve as a to-be-processed image; performing denoising processing on each to-be-processed image through a preset denoising module to obtain a denoised image feature corresponding to each to-be-processed image; inputting each denoised image feature into a preset super-resolution reconstruction module, obtaining a target image output by the super-resolution reconstruction module, and the resolution of the target image being larger than that of the to-be-processed image; and generating a target video frame sequence according to the target image corresponding to each to-be-processed image. According to the invention, the to-be-processed image is subjected to targeted denoising before image super-resolution reconstruction, so that the image noise can be prevented from being amplified in the reconstruction process, the image quality of the target image after super-resolution reconstruction can be improved, and the image quality of the processed video is further improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and more specifically, to an image processing method, device, electronic equipment, and storage medium. Background technique [0002] Super-resolution reconstruction (Super-Resolution, SR), also known as super-resolution reconstruction, refers to the method of improving the resolution of the original image and reconstructing the low-resolution image into a high-resolution image. For the processing of video images, usually the image is directly sent to a neural network model for training, so as to achieve super-resolution reconstruction. But in this process, super-resolution reconstruction will also enhance the noise while enlarging the image, which affects the overall quality of the output image, and cannot make the final video image achieve a better display effect. Therefore, it is necessary to optimize the image super-resolution reconstruction process. Contents of t...
