On the Utility of 3D Hand Poses for Action Recognition
3D hand poses are an under-explored modality for action recognition.
Masked Motion Predictors are Strong 3D Action Representation Learners
To be specific, the proposed MAMP takes as input the masked spatio-temporal skeleton sequence and predicts the corresponding temporal motion of the masked human joints.
Interactive Spatiotemporal Token Attention Network for Skeleton-based General Interactive Action Recognition
To address these problems, we propose an Interactive Spatiotemporal Token Attention Network (ISTA-Net), which simultaneously model spatial, temporal, and interactive relations.
CMD: Self-supervised 3D Action Representation Learning with Cross-modal Mutual Distillation

•
In this work, we formulate the cross-modal interaction as a bidirectional knowledge distillation problem.
Collaborating Domain-shared and Target-specific Feature Clustering for Cross-domain 3D Action Recognition
canbaoburen/CoDT
•
•
Furthermore, to leverage the complementarity of domain-shared features and target-specific features, we propose a novel collaborative clustering strategy to enforce pair-wise relationship consistency between the two branches.
Multi-Scale Spatial Temporal Graph Convolutional Network for Skeleton-Based Action Recognition
czhaneva/mst-gcn
•
•
To solve this problem, we present a multi-scale spatial graph convolution (MS-GC) module and a multi-scale temporal graph convolution (MT-GC) module to enrich the receptive field of the model in spatial and temporal dimensions.
PSTNet: Point Spatio-Temporal Convolution on Point Cloud Sequences

ICLR 2021
Then, a spatial convolution is employed to capture the local structure of points in the 3D space, and a temporal convolution is used to model the dynamics of the spatial regions along the time dimension.
Assembly101: A Large-Scale Multi-View Video Dataset for Understanding Procedural Activities
Assembly101 is a new procedural activity dataset featuring 4321 videos of people assembling and disassembling 101 "take-apart" toy vehicles.
No Pain, Big Gain: Classify Dynamic Point Cloud Sequences with Static Models by Fitting Feature-level Space-time Surfaces

CVPR 2022
Scene flow is a powerful tool for capturing the motion field of 3D point clouds.
Domain Knowledge-Informed Self-Supervised Representations for Workout Form Assessment
To that end, we propose to learn exercise-oriented image and video representations from unlabeled samples such that a small dataset annotated by experts suffices for supervised error detection.
