Title:
VIDEO ENCODING AND DECODING METHOD AND APPARATUS, DEVICE, SYSTEM AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/206420
Kind Code:
A1
Abstract:
Embodiments of the present application provide a video encoding and decoding method and apparatus, a device, a system and a storage medium. To improve the accuracy of a reconstructed image, multi-stage time domain fusion is carried out on quantized first feature information, that is, the quantized first feature information is not only fused with feature information of a previous reconstructed image of the current image, and performs feature fusion on the quantized first feature information and a plurality of reconstructed images before the current image, so as to avoid the shielded information being obtained from a plurality of reconstructed images before the current image when certain information in the previous reconstructed image of the current image is shielded, such that the generated mixed spatiotemporal representation comprises more accurate, rich and detailed feature information. In this way, when motion compensation is carried out on the previous reconstructed image on the basis of the mixed spatiotemporal representation, when P predicted images with high precision can be generated, a reconstructed image of the current image can be accurately obtained on the basis of the P predicted images with high precision, and then the video compression effect is improved.
