Statistical Analysis of Inter Coding in VVC Test Model (VTM)

The promising compression efficiency improvement of Versatile Video Coding (VVC) compared to High Efficiency Video Coding (HEVC) [1] comes at the cost of a non-negligible encoder-side complexity. The largely increased complexity overhead is a possible obstacle towards its industrial implementation. Many papers have proposed acceleration methods for VVC. Still, a better understanding of VVC complexity, especially related to new partitions and coding tools, is desirable to help the design of new and better acceleration methods. For this purpose, statistical analyses have been conducted, with a focus on Coding Unit (CU) sizes and inter coding modes.
