Prior-Gated Adaptation With Multi-Granularity Structural Refinement for Fine-Grained Infrared Small-Target Segmentation

Accurate infrared small-target segmentation is an inherently challenging low signal-to-noise ratio task, where targets occupy only a few pixels and are often obscured by weak responses, ambiguous boundaries, and complex clutter. Although vision foundation models offer transferable representations, their direct adaptati...

Multimodal Action Recognition via Causality-Inspired Graph Representation Learning

Multimodal human activity recognition (HAR) benefits from complementary skeleton, inertial, and visual observations. However, many learning-based models still treat relationships among modalities, joints, and sensor variables as symmetric associations. This limits their ability to represent asymmetric information flow...
