Comparative Performance and Parameter-Efficient Adaptation of DINOv2 for Active Trachoma Classification
Kibrom Gebremedhin, Hadush Hailu, Bruk Gebregziabher +1
Automated grading of conjunctival photographs could reduce the cost and variability of trachoma prevalence surveys, but the relative value of modern pretrained visual representatio…
OPTED: Open Preprocessed Trachoma Eye Dataset Using Zero-Shot SAM 3 Segmentation
Kibrom Gebremedhin, Hadush Hailu, Bruk Gebregziabher
Trachoma remains the leading infectious cause of blindness worldwide, with Sub-Saharan Africa bearing over 85% of the global burden and Ethiopia alone accounting for more than half…
Quantifying Motion Excitation for Metric Scale Observability in Monocular Visual-Inertial Odometry
Hadush Hailu, Bruk Gebregziabher, Siddhartha Gudipudi +1
Monocular visual-inertial odometry (VIO) cannot recover metric scale from vision alone; scale must be resolved through inertial measurements. We present a trajectory-dependent obse…
