This paper reviews the evolution and application of in-loop filters in video coding standards, focusing on cross-component filters. Initially, filters like the Deblocking Filter and Sample Adaptive Offset operated independently on different components. More recently, cross-component filters have been developed to enhance chroma fidelity by leveraging the correlation between luma and chroma channels. The paper details the Cross-Component Adaptive Loop Filter and Cross-Component Sample Adaptive Offset, explaining their role in reducing compression artifacts and improving pixel reconstruction. AI
