Pose-aware Attention Network for Flexible Motion Retargeting by Body Part

1 code implementation13 Jun 2023 Lei Hu, Zihao Zhang, Chongyang Zhong, Boyuan Jiang, Shihong Xia

Moreover, we also show that our framework can generate reasonable results even for a more challenging retargeting scenario, like retargeting between bipedal and quadrupedal skeletons because of the body part retargeting strategy and PAN.

Spatio-Temporal Gating-Adjacency GCN for Human Motion Prediction

no code implementations CVPR 2022 Chongyang Zhong, Lei Hu, Zihao Zhang, Yongjing Ye, Shihong Xia

However, considering the variants and diverse action types in human motion data, the cross-dependency of the spatio-temporal relationships will be difficult to depict due to the decoupled modeling strategy, which may also exacerbate the problem of insufficient generalization.
