Bike Detection Subset
Dataset Description
This dataset is a small public subset of a private bicycle detection dataset used for embedded computer vision experiments.
It contains 200 grayscale QQVGA images:
- 100 positive samples containing at least one bicycle
- 100 negative samples without bicycles
The images have a resolution of:
160 × 120
and are stored as grayscale images.
Dataset Structure
Each sample contains:
image
image_id
task
sample_type
width
height
objects
sample_type is either:
positive
negative
The objects field contains:
bbox
category
Bounding boxes use the format:
[x, y, width, height]
with coordinates expressed in pixels.
The bicycle class is represented with category ID:
0
Negative samples contain no bounding boxes.
Example
{
"image": ...,
"image_id": "task_01_image_001",
"task": "task_01",
"sample_type": "positive",
"width": 160,
"height": 120,
"objects": {
"bbox": [
[34.0, 21.0, 48.0, 71.0]
],
"category": [

]
}
}
Dataset Creation
The samples were randomly selected from a larger private dataset.
The original data consists of low-resolution grayscale images prepared for an embedded bicycle detection use case.
Annotations were originally stored in YOLO format and converted to pixel-space bounding boxes when generating this Hugging Face dataset.
Intended Use
This subset is intended for:
- Demonstrating the associated bicycle detection model
- Testing dataset loading and preprocessing pipelines
- Embedded computer vision experiments
- Bicycle object detection examples
It is not intended to be a comprehensive benchmark dataset.
Limitations
This dataset contains only 200 samples and represents a limited subset of the original private dataset.
It may not cover the full diversity of:
- Lighting conditions
- Camera viewpoints
- Bicycle appearances
- Backgrounds
- Object scales
- Acquisition environments
Performance measured on this subset should therefore not be considered representative of general bicycle detection performance.
Source Dataset
The complete training dataset is private and is not distributed with this repository.
