Title:
IMAGE ENCODING DEVICE, IMAGE DECODING DEVICE, IMAGE PROCESSING SYSTEM, MODEL LEARNING DEVICE, IMAGE ENCODING METHOD, IMAGE DECODING METHOD, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/084660
Kind Code:
A1
Abstract:
In the present invention, a first machine learning model is used on image data to extract context information indicating characteristics of the image data, a second machine learning model is used on the context information to determine parameters for a third machine learning model, the third machine learning model is used on the image data to generate compressed data having a smaller amount of information than the image data, and the context information and the compressed data are encoded to generate a code sequence. The context information and the compressed data are decoded from the code sequence, a fourth machine learning model is used on the context information to determine parameters for a fifth machine learning model, and the fifth machine learning model is used on the compressed data to generate restored data.
