This study contributes to advancing the understanding and implementation of film grain handling techniques in VVC open-source implementations, with implications for enhancing the viewing experience in multimedia applications.
In recent years, the proliferation of high-definition video content across various platforms has led to an increased focus on optimizing video coding standards to achieve higher compression efficiency and improved visual quality. The Versatile Video Coding (VVC) standard, developed by the Joint Video Experts Team (JVET) of the International Telecommunication Union (ITU) and the Moving Picture Experts Group (MPEG), represents the latest advancement in video compression technology. VVC offers significant improvements over its predecessors, such as High Efficiency Video Coding (HEVC), regarding compression efficiency, flexibility, and support for emerging multimedia applications.
This paper presents an in-depth analysis of film grain handling in open source implementations of the Versatile Video Coding (VVC) standard. We focus on two key components: the Film Grain Analysis (FGA) module implemented in VVenC and the Film Grain Synthesis (FGS) module implemented in VVdeC. We describe the methodologies used to implement these modules and discuss the generation of Supplementary Enhancement Information (SEI) parameters to signal film grain characteristics in the encoded video sequences. Additionally, we conduct subjective and objective evaluations across Full HD videos to assess the effectiveness of film grain handling. Our results demonstrate...
