DATA PROCESSING METHOD AND APPARATUS, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/016775
Kind Code:
A1
Abstract:
Embodiments of the present application provide a data processing method and apparatus, and a device. The method comprises: determining classification mode information corresponding to a block to be coded in video data, the classification mode information comprising an extended co-located luma reconstructed pixel corresponding to a color component pixel in said block and a target classification mode, and the extended co-located luma reconstructed pixel belonging to a target area centered on a real co-located luma reconstructed pixel of the color component pixel; determining a boundary category corresponding to the color component pixel according to the extended co-located luma reconstructed pixel and the target classification mode; and compensating a reconstructed pixel of the color component pixel on the basis of the boundary category to obtain a compensated reconstructed pixel, and coding said block on the basis of the compensated reconstructed pixel. By adopting the embodiments of the present application, the accuracy of compensation for the boundary category corresponding to the color component pixel can be improved, and thus improving the overall coding performance of the video data.
