AI Technical Summary
Technical Problem
Existing video coding technologies face inefficiencies in compressing video data due to the limitations of using a single intra-prediction mode, which can lead to suboptimal transform selection and reduced coding efficiency.
Method used
The method involves intra-prediction fusion, where multiple candidate intra-prediction modes are used to derive a dominant mode, and a transform set associated with this mode is applied to the current block, enhancing coding efficiency by selecting appropriate transforms based on frequency analysis or template matching.
Benefits of technology
This approach improves video coding efficiency by optimizing transform selection, leading to better compression and quality of decoded video data.

Abstract
Aspects of the present disclosure include methods and devices for video coding. One of the devices includes a processing circuit that receives a current block in a bitstream. The current block is predicted by intra-prediction fusion including multiple candidate intra-prediction modes. The processing circuit derives a dominant intra-prediction mode from the multiple candidate intra-prediction modes. The processing circuit applies a transform from a transform set associated with the dominant intra-prediction mode to the current block and decodes the current block according to the transform.
