Document Type and Number:
WIPO Patent Application WO/2019/141258
Kind Code:
A1
Abstract:
The present application relates to a video encoding method, a video decoding method, a device, and a system, pertaining to the field of video encoding and decoding. The method comprises: acquiring a distorted image and an edge information component corresponding to the distorted image, and inputting the distorted image and the edge information component into a convolutional neural network model to perform filtering processing so as to obtain a first undistorted image block corresponding to a distorted image block comprised in the distorted image; selecting one image block from at least one image block corresponding to the distorted image block to be a target undistorted image block of the distorted image block, the at least one image block comprising the first undistorted image block corresponding to the distorted image block and/or the distorted image block; and encoding, according to an undistorted image block corresponding to each distorted image block comprised in the distorted image, an original video image following a current original video image to obtain a video bit stream. The present application improves the performance of image distortion removal.
