New method calibrates object detectors using annotator disagreement

Researchers have developed a new method to calibrate probabilistic object detectors, specifically addressing challenges posed by annotator disagreement on ambiguous objects. This approach allows detectors to be trained and evaluated without relying on a definitive ground truth, instead aligning model confidence and bounding box variance with the distribution of multiple annotator labels. The framework introduces novel evaluation metrics and both train-time and post-hoc calibration techniques, demonstrating effectiveness across various object detectors and datasets. AI

IMPACT This research could improve the reliability of object detection models in domains with inherent ambiguity, such as medical imaging.
