LoRIS - Weakly-Supervised Anomaly Detection for Ultrasound Images
LoRIS is a weakly-supervised anomaly detection method for knee ultrasound images. Trained only on nondistended cases, it uses a location prior to guide reconstruction and detect anomalies. It outperforms unsupervised methods and matches supervised ones—without needing segmentation annotations or images from both classes.
