PROCESSING IMAGE DATA

原文（中国語）

A method of processing image data, comprising receiving, at a pre-processing artificial neural network, ANN, image data of one or more images, pre-processing the received image data at the pre-processing ANN to generate pre-processed image data of the one or more images, encoding and decoding, in accordance with an image or video codec, the pre-processed image data to generate decoded image data of the one or more images, and post-processing the decoded image data at a post-processing ANN to generate post-processed image data of the one or more images. The pre-processing ANN and the post-processing ANN are jointly trained in an end-to-end manner using a neural codec model arranged between the pre-processing ANN and the post-processing ANN, the neural codec model acting as a proxy for the image or video codec and comprising an ANN configured to emulate rate and distortion characteristics of the image or video codec.
