TransSLR: A Lightweight Transformer for Sign Language Recognition
Lucia Yen Wanchi, Samuel Johnny, Victor Tolulope Olufemi +2
Automated Sign Language Recognition for under-represented languages remains a largely unsolved problem. Central African Sign Language (CASL) exemplifies this gap: the only availabl…
Towards Fair and Robust Volumetric CT Classification via KL-Regularised Group Distributionally Robust Optimisation
Samuel Johnny, Blessed Guda, Goodness Obasi +2
Automated diagnosis from chest computed tomography (CT) scans faces two persistent challenges in clinical deployment: distribution shift across acquisition sites and performance di…
Prompt-Free SAM-Based Multi-Task Framework for Breast Ultrasound Lesion Segmentation and Classification
Samuel E. Johnny, Bernes L. Atabonfack, Israel Alagbe +1
Accurate tumor segmentation and classification in breast ultrasound (BUS) imaging remain challenging due to low contrast, speckle noise, and diverse lesion morphology. This study p…
Pose-Based Sign Language Spotting via an End-to-End Encoder Architecture
Samuel Ebimobowei Johnny, Blessed Guda, Emmanuel Enejo Aaron +1
Automatic Sign Language Recognition (ASLR) has emerged as a vital field for bridging the gap between deaf and hearing communities. However, the problem of sign-to-sign retrieval or…
AutoSign: Direct Pose-to-Text Translation for Continuous Sign Language Recognition
Samuel Ebimobowei Johnny, Blessed Guda, Andrew Blayama Stephen +1
Continuously recognizing sign gestures and converting them to glosses plays a key role in bridging the gap between the hearing and hearing-impaired communities. This involves recog…
