Researchers have developed a novel training-free framework designed to classify and localize anomalies in prenatal ultrasound images. This method utilizes a memory bank with multi-granular prototypes to capture class semantics and anomaly characteristics, enabling detection with only a few reference images per class. The framework includes a prototype-driven soft merging mechanism for feature aggregation and a class-aware refinement strategy for improved prediction, outperforming existing methods on a multi-center dataset.
