Title:
METHOD AND DEVICE FOR IMAGE ENCODING/DECODING, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/058642
Kind Code:
A1
Abstract:
A method and a device for image encoding/decoding, and a recording medium are provided. The image decoding method according to an embodiment may comprise the steps of: decoding encoded information so as to acquire information about a neural network; using the information about the neural network so as to select a neural network; and using the selected neural network so as to decode a target. Here, a neural network can be trained. The neural network training can include at least one from among prior training, data augmentation training, and attention-guided training. The neural network can be a deep neural network of an in-loop filter for in-loop filtering.
