New VVC framework optimizes adaptive loop filter for faster video compression

Researchers have developed an optimized framework for the Adaptive Loop Filter (ALF) in Versatile Video Coding (VVC). This new framework includes parallel designs for Geometry transformation-based Adaptive Loop Filter (GALF) and Cross Component Adaptive Loop Filter (CCALF), along with adaptive parameter decision for GALF and a one-pass CCALF scheme. The proposed method significantly reduces picture buffer access and achieves approximately 25% time savings in the ALF module with minimal impact on coding performance. AI

IMPACT Improves video compression efficiency, potentially impacting AI-driven video processing pipelines.
