Training Framework

This model was trained using DetectionBench, an open-source framework for benchmarking object detectors across multiple real-world datasets with a common pipeline.

Features include:

A dataset-adapter registry for converting real-world datasets into a canonical format
Identical training/evaluation recipes across model families (Ultralytics YOLO/RT-DETR, RF-DETR)
Hardware profiling (latency, FPS, VRAM, parameters, FLOPs)
One-command reproducibility via versioned Hydra configs

Known Limitations

Severe class imbalance: car (94.6%) dominates the annotated boxes, while truck (3.1%) and bus (2.3%) are rare -- per-class accuracy on the minority classes is measured on comparatively few examples, and every model here scores far lower on them than on car.
Very small objects: the median box covers only 0.14% of the image area (mean 0.26%), so this is a hard small-object regime and absolute mAP values are low for every architecture; the numbers are best read as a relative comparison between models, not as a production-quality detector.
Video-derived, highly correlated frames: the ~40.7k labelled images come from 50 video sequences, so consecutive frames are near-duplicates. UAVDT's 50 tracking-only sequences have no detection labels and are excluded. The validation split is carved out of the training sequences by sequence (not by frame) to avoid leakage, but effective diversity is far lower than the image count suggests.
Different density per split: instances per image are 15.7 (train), 28.0 (valid) and 22.7 (test), because the splits contain different sequences -- validation metrics are not directly predictive of test metrics.
Research-use-only data: UAVDT is distributed "for research purpose only" with no redistribution grant, so the dataset is not mirrored here -- obtain it from the official source (see the Dataset section above) and check its terms before any use beyond research.
