Traditional codecs [HM (JVET/HM, 2024) and VTM (VCGIT, 2024)] are indicated by dashed lines for reference. For broader context, pioneering methods DVC (Lu et al., 2018), DVC-Pro (Lu et al., 2020), DCVC (Li et al., 2021), DHVC (Lu et al., 2023), and CANF-VC (Ho et al., 2022), proposed before and after VCT are also included for broader comparison. The performance metrics for HM-16.26 are adopted from the DHVC paper (Lu et al., 2023) and VTM-13.2 results are adopted from the benchmarks reported in DCVC-TCM (Sheng et al., 2021)
