Part-aware Prototypical Graph Network for One-shot Skeleton-based Action Recognition

no code implementations19 Aug 2022 Tailin Chen, Desen Zhou, Jian Wang, Shidong Wang, Qian He, Chuanyang Hu, Errui Ding, Yu Guan, Xuming He

In this paper, we study the problem of one-shot skeleton-based action recognition, which poses unique challenges in learning transferable representation from base classes to novel classes, particularly for fine-grained actions.

Human-Object Interaction Detection via Disentangled Transformer

no code implementations CVPR 2022 Desen Zhou, Zhichao Liu, Jian Wang, Leshan Wang, Tao Hu, Errui Ding, Jingdong Wang

To associate the predictions of disentangled decoders, we first generate a unified representation for HOI triplets with a base decoder, and then utilize it as input feature of each disentangled decoder.

Automatic spinal curvature measurement on ultrasound spine images using Faster R-CNN

no code implementations17 Apr 2022 Zhichao Liu, Liyue Qian, Wenke Jing, Desen Zhou, Xuming He, Edmond Lou, Rui Zheng

The framework consisted of two closely linked modules: 1) the lamina detector for identifying and locating each lamina pairs on ultrasound coronal images, and 2) the spinal curvature estimator for calculating the scoliotic angles based on the chain of detected lamina.

LSTA-Net: Long short-term Spatio-Temporal Aggregation Network for Skeleton-based Action Recognition

no code implementations1 Nov 2021 Tailin Chen, Shidong Wang, Desen Zhou, Yu Guan

We devise our model into a pure factorised architecture which can alternately perform spatial feature aggregation and temporal feature aggregation.

Single Image 3D Object Estimation with Primitive Graph Networks

1 code implementation9 Sep 2021 Qian He, Desen Zhou, Bo Wan, Xuming He

To address those challenges, we adopt a primitive-based representation for 3D object, and propose a two-stage graph network for primitive-based 3D object estimation, which consists of a sequential proposal module and a graph reasoning module.

Pose-aware Multi-level Feature Network for Human Object Interaction Detection

1 code implementation ICCV 2019 Bo Wan, Desen Zhou, Yongfei Liu, Rongjie Li, Xuming He

Reasoning human object interactions is a core problem in human-centric scene understanding and detecting such relations poses a unique challenge to vision systems due to large variations in human-object configurations, multiple co-occurring relation instances and subtle visual difference between relation categories.
