Metric Knowledge Distillation for Zero-Shot Cross-Domain Fine-Grained Pill Identification
Pill recognition is hard across regions: training and deployment images differ across regulatory standards (e.g., U.S. FDA vs. Hungary’s OGYEIv2), and smartphone-budget compact models often lose accuracy on out-of-region pills. We benchmark 31 deep architectures on a U.S. source dataset (ePillID) and evaluate zero-shot...
