AIDOVECL: AI-generated Dataset of Outpainted Vehicles for Eye-level Classification and Localization

We introduce an annotated AI-generated dataset of eye-level vehicle images using outpainting, offering versatile generation of diverse vehicle classes in varied contexts with pretrained models.

Dataset Details

Dataset Description

Our dataset consists of AI-generated, eye-level vehicle images created by detecting and cropping vehicles from manually chosen and classified seed images. These vehicles are then outpainted onto larger canvases to replicate diverse real-world scenarios. The resulting images are meticulously annotated automatically, offering high-quality ground truth data. Through the use of sophisticated outpainting techniques and stringent image quality assessments, we ensure exceptional visual fidelity and contextual accuracy. Moreover, the efficiency and utility of the dataset are demonstrated through benchmark experiments presented in the accompanying paper.

Dataset Sources

Uses

Direct Use

This curated dataset combines real, manually classified vehicle images with AI-generated outpainted variants, offering a diverse yet structured resource for computer vision and mobility-related applications. The images maintain contextual plausibility and consistent labeling, making the dataset suitable for training, evaluation, and augmentation workflows. In autonomous driving, it supports vehicle detection and recognition by exposing models to varied environments and viewpoints. The inclusion of fine-grained classes—reflecting differences in vehicle size, passenger capacity, and utility—enables more detailed analysis in urban planning and transportation modeling, such as estimating fleet composition, mode share, and curb usage. For environmental research, the dataset facilitates modeling of vehicle-type-specific emissions and spatial distribution patterns. By combining real-world fidelity with scalable synthetic augmentation, it contributes to more reproducible and generalizable pipelines across both technical and policy-oriented domains.

Out-of-Scope Use

While the dataset improves access to diverse and well-annotated vehicle imagery, it is not intended for all uses. Malicious or unethical applications—such as unauthorized surveillance or activities that infringe on privacy—are strictly prohibited. The dataset is most suitable for domains like autonomous driving, urban planning, and environmental monitoring, where the vehicle-level annotations and scene contexts are relevant. Applying it in unrelated fields, especially those misaligned with its structure or labeling scheme, may lead to poor performance or misleading outcomes.

Dataset Structure

The root directory contains the augmented dataset, curated by manually excluding rare generation failures to ensure aesthetic quality and realism, and organized into train, val, and test splits. In contrast, the datasets.zip archive contains the benchmarking datasets used in the paper, structured for reproducibility. It includes real_raw, which holds the original manually classified images grouped by vehicle type; real, a YOLO-formatted selection of these images with corresponding labels and a configuration file (real.yaml); and augmented, which extends the real set with AI-generated outpainted images and labels, accompanied by augmented.yaml.

Dataset Creation

Curation Rationale

Publicly available vehicle recognition datasets have driven progress in the field but often fall short in key areas, including lacking contextual richness, offering limited vehicle classifications, and presenting suboptimal viewing angles. These shortcomings underscore the necessity for customizable vehicle datasets tailored to meet the specific requirements of contemporary vehicle recognition applications.

Personal and Sensitive Information

To the best of our knowledge, the dataset does not contain information that is likely to be personal or sensitive, nor is any content intended to identify individuals.

Bias, Risks, and Limitations

Our dataset currently cannot outpaint multiple vehicles in a single image due to the limitations of the inpainting model, which struggles with generating coherent scenes with multiple vehicles. This also stems from the challenge of selecting seed images that naturally correlate. Consequently, our dataset lacks rich occlusion scenarios crucial for training robust detection systems. Additionally, our reliance on pretrained detection and inpainting models means that objects not included in the original model training may be missed or appear unrealistic. We also face a shortage of seed images, especially for certain vehicle classes like vans, leading to class imbalances. Addressing these issues is crucial for improving our dataset's effectiveness and the accuracy of detection models.

Recommendations

As future work, we recommend exploring more advanced generative methods or complementary augmentations to better capture multi-vehicle and occlusion scenarios, expanding seed image collections to address class imbalance, and fine-tuning pretrained models with domain-specific data for broader coverage. These efforts should be paired with systematic quality checks, human oversight, and transparent documentation to ensure realism, mitigate bias, and guide appropriate dataset use.
