## **OpenDetection-15K-Dense-v2.0**

**OpenDetection-15K-Dense-v2.0** is an object detection dataset built primarily from general, publicly available images, which make up the majority of the input imagery, together with additional publicly available datasets. The dataset contains high-quality object detection annotations generated using modern automated computer vision pipelines, providing structured object labels, confidence scores, and bounding box coordinates for every detected object. Each sample includes the original image, machine-readable detection annotations, and a rendered visualization with all detected objects overlaid on the image. Version 2.0 contains a different curated subset of images while maintaining the same annotation format and dataset structure, making it suitable for training, evaluation, benchmarking, and multimodal computer vision research. The dataset is distributed using the Hugging Face Datasets format with optimized Parquet files for efficient loading and large-scale machine learning workflows.

## Dataset Statistics

| Property | Value |
|-----------|-------|
| Number of Samples | 14,911 |
| Image Format | RGB |
| Annotation Format | JSON |
| Visualization | Annotated Image |
| Dataset Format | Optimized Parquet |

## Dataset Structure

Each sample contains the following fields:

| Column | Type | Description |
|---------|------|-------------|
| `image` | Image | Original input image |
| `objects` | List | Object detection annotations containing labels, label IDs, confidence scores, and bounding boxes |
| `annotated_image` | Image | Visualization of the image with rendered bounding boxes |

Example:

```python
sample = ds[0]

print(sample.keys())

# dict_keys([
#     "image",
#     "objects",
#     "annotated_image"
# ])
```

## Loading the Dataset

```python
from datasets import load_dataset

ds = load_dataset(
    "prithivMLmods/OpenDetection-15K-Dense-v2.0",
    split="train"
)
```

## Example Usage

```python
from datasets import load_dataset
import matplotlib.pyplot as plt

ds = load_dataset(
    "prithivMLmods/OpenDetection-15K-Dense-v2.0",
    split="train"
)

sample = ds[0]

image = sample["image"]
objects = sample["objects"]
annotated = sample["annotated_image"]

print("Detected Objects:")
print(objects)

fig, axes = plt.subplots(1, 2, figsize=(12, 6))

axes[0].imshow(image)
axes[0].set_title("Image")
axes[0].axis("off")

axes[1].imshow(annotated)
axes[1].set_title("Annotated Image")
axes[1].axis("off")

plt.show()
```
