Detector sensitivity curves for the YOLO-CIANNA model. The top frames represent purity-completeness curves built from running purity and precision scores on an objectness-sorted prediction list. The smoothed version considers that the purity at any completeness point is the maximum purity at any superior completeness. The bottom frames represent the binned purity as a function of the objectness for each detection unit. The bin size is 0.01, 0.05, and 0.1 for the small, intermediate, and large size-prior regimes, respectively. The left and right columns present curves produced with the SDC1 scorer matching rule and a purely geometrical DIoU-based with a 0.1 threshold matching rule, respectively. All curves are produced from the same candidate catalog where all detections with an objectness less than 0.03 have been removed.
