HopFIR: Hop-wise GraphFormer with Intragroup Joint Refinement for 3D Human Pose Estimation

no code implementations28 Feb 2023 Kai Zhai, Qiang Nie, Bo Ouyang, Xiang Li, Shanlin Yang

The HopFIR mainly consists of a novel Hop-wise GraphFormer(HGF) module and an Intragroup Joint Refinement(IJR) module which leverages the prior limb information for peripheral joints refinement.
