The latest UVG paper introduces a novel open-source V-PCC encoder, named uvgVPCCenc, that brings V-PCC compression speed to a practical level. This paper received the Best Open Dataset and Software Paper Award from the ACM Multimedia Systems Conference in April 2025.
The paper about Versatile Video Coding (VVC), on the other hand, received the Best Paper Award from the IEEE International Conference on Visual Communications and Image Processing (VCIP) in December 2024. VVC provides new coding tools for more efficient intra prediction but with a substantial increase in computational complexity. The paper introduces vectorized kernels for 8-bit angular intra prediction and position dependent intra prediction combination (PDPC), which are carefully optimized for all block sizes and prediction modes of VVC.
