FineX method advances fine-grained action recognition with novel fusion techniques

Researchers have introduced FineX, a novel method for fine-grained human action recognition. This approach effectively distinguishes between visually similar actions by integrating RGB appearance, pose heatmap geometry, and skeletal-graph topology. FineX utilizes pairwise cross-attention for information exchange between these representations and a latent sparse Mixture-of-Experts to route data to relevant experts. The method has demonstrated state-of-the-art performance on benchmark datasets like Gym99, Gym288, and Diving48, significantly improving mean class accuracy on the long-tailed Gym288 dataset. AI
