FineSkiing: A Fine-grained Benchmark for Skiing Action Quality Assessment
Yongji Zhang, Siqi Li, Yue Gao +1
Action Quality Assessment (AQA) aims to evaluate and score sports actions, which has attracted widespread interest in recent years. Existing AQA methods primarily predict scores ba…
H3Former: Hypergraph-based Semantic-Aware Aggregation via Hyperbolic Hierarchical Contrastive Loss for Fine-Grained Visual Classification
Yongji Zhang, Siqi Li, Kuiyang Huang +2
Fine-Grained Visual Classification (FGVC) remains a challenging task due to subtle inter-class differences and large intra-class variations. Existing approaches typically rely on f…
Dynamic Spatial-temporal Hypergraph Convolutional Network for Skeleton-based Action Recognition
Shengqin Wang, Yongji Zhang, Hong Qi +2
Skeleton-based action recognition relies on the extraction of spatial-temporal topological information. Hypergraphs can establish prior unnatural dependencies for the skeleton. How…
Skeleton-based Action Recognition via Temporal-Channel Aggregation
Shengqin Wang, Yongji Zhang, Minghao Zhao +4
Skeleton-based action recognition methods are limited by the semantic extraction of spatio-temporal skeletal maps. However, current methods have difficulty in effectively combining…
