Human Action Recognition in Multi-Level Convolutional Temporal Attention Network

Qian Huang, Zhongqi Chen, Chang Li, Weiwen Qian

ICASSP 2025accepted

Human Action Recognition (HAR) has widespread applications in areas such as human-computer interaction, elderly care, and home healthcare. However, current sensor-based HAR faces challenges of low fine-grained recognition performance and difficulty in distinguishing similar actions. To solve this pr…

PASTD: Progressive Augmentation and Spatiotemporal Decoupling Contrastive Learning for Skeleton-Based Action Recognition

Qian Huang, Weiwen Qian, Chang Li, Gongyou Xu, Zhongqi Chen

ICASSP 2025accepted

Contrastive learning has achieved significant progress in the field of self-supervised skeleton-based action recognition. However, existing methods often apply strong augmentations directly to skeleton data, which can distort or even lose the semantic of the skeletons. Additionally, most methods foc…
