Replication bundle: The 0.43 IoU Ceiling of Axis-Aligned Boxes — Geometry-Matched Detection for Scenes That Mix Rotated and Circular Objects

Data, trained weights, and code accompanying the manuscript "The 0.43 IoUCeiling of Axis-Aligned Boxes: Geometry-Matched Detection for Scenes That MixRotated and Circular Objects". Contains the common ground-truth annotationsfor the 3,180-image synthetic test split, the stored test-set predictions offour YOLO11 detectors that differ only in bounding-box geometry, 228 annotatedreal photographs, the four sets of trained weights, and the evaluation andtraining code — including the common-ground-truth polygon-IoU evaluator. Thetables in the paper can be recomputed from the stored predictions without aGPU.
