Fine-Grained Action Recognition with Cross-Attentive Latent Sparse Experts
Imtiaz Ul Hassan, Tasweer Ahmad, Nik Bessis +1
Fine-grained human action recognition (FHAR) must distinguish visually similar actions that differ mainly in body configuration, timing, or local appearance. RGB representations re…
Language-Structured Relational Q-Learning for Threat-Aware Control in Safety-Critical Driving
Aditya Humnabadkar, Huaizhong Zhang, Ardhendu Behera
Natural-language-based scenario generation offers an intuitive means of describing rare and complex driving interactions, yet it is still uncertain whether training with language-s…
Geometry-Aware Superpixel Graph Transformer with Metadata for Skin Lesion Classification
Muhammad Azeem, Tanveer Hussain, Amr Ahmed +1
Automated skin cancer classification from dermoscopic images remains challenging due to heterogeneous lesion structure, strong intra-class variability, and subtle visual difference…
ATRACT: A Trustworthy Robotic Autonomous system to support Casualty Triage
Tasweer Ahmad, Rafael Pina, Sandip Pradhan +6
At a time when drones are increasingly associated with hostile operations, we re-purpose them for humanitarian and life-saving applications. However, adapting search and rescue dro…
Towards Label-Free Single-Cell Phenotyping Using Multi-Task Learning
Saqib Nazir, Ardhendu Behera
Label-free single-cell imaging offers a scalable, non-invasive alternative to fluorescence-based cytometry, yet inferring molecular phenotypes directly from bright-field morphology…
TAG-Head: Time-Aligned Graph Head for Plug-and-Play Fine-grained Action Recognition
Imtiaz Ul Hassan, Nik Bessis, Ardhendu Behera
Fine-grained human action recognition (FHAR) is challenging because visually similar actions differ by subtle spatio-temporal cues. Many recent systems enhance discriminability wit…
