YOLOv8s Finetuned on KITTI

Fine-tuned YOLOv8s object detector on the KITTI benchmark dataset, trained and evaluated as part of DetectionBench -- a framework for reproducibly benchmarking modern object detectors with identical training recipes and evaluation metrics across multiple real-world datasets.

Usage

Install Dependencies

pip install ultralytics huggingface_hub

Load Model from Hugging Face

from huggingface_hub import hf_hub_download
from ultralytics import YOLO

weights = hf_hub_download(
    repo_id="dronefreak/kitti-yolov8s",
    filename="best.pt"
)

model = YOLO(weights)

Run Inference

results = model.predict(
    source="image.jpg",
    conf=0.25
)

results[0].show()

Performance

Evaluated on the KITTI val split, using DetectionBench's standard evaluation pipeline (detectionbench-evaluate).

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

• No official test-set labels: KITTI's real held-out test images have never had public ground truth, so this adapter (following the field-standard Chen et al. 2015 3DOP split) uses train (3,712) / valid (3,769) only -- "valid" is both the early-stopping signal and the split all metrics on this card are computed on, the same convention the wider KITTI detection literature uses.
• Severe class imbalance across 8 classes: Car is 70.8% of all boxes, while Person_sitting has only 222 instances (0.5%) across all 7,481 images -- its per-class score is measured on very few examples and should be read with caution.
• Unusual native aspect ratio: frames are ~1242x375 (~3.3:1, not the usual 4:3/16:9), so square-letterboxed training/inference wastes canvas on padding above and below the real content; a higher input resolution (see Training Configuration) partly compensates for the resulting loss of effective resolution.
• Small dataset for the task's difficulty: only 3,712 training images across a real (non-memorization-prone) street-scene detection task, so absolute scores are lower than on datasets with more training data or an easier task shape.
• Demo banner is not KITTI's own labelled data: the video above uses KITTI's official but unlabelled tracking-benchmark sequences (0000-0028.mp4) for illustration, run through the model at inference time -- it is not part of the train/valid split and the boxes shown are the model's raw predictions, not checked against ground truth.
