OpenDetection-15K-Dense-v1.0

OpenDetection-15K-Dense-v1.0 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. The dataset is intended for training, evaluation, benchmarking, and multimodal computer vision research, and is distributed using the Hugging Face Datasets format with optimized Parquet files for efficient loading and large-scale machine learning workflows.

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:

sample = ds[0]

print(sample.keys())

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

Loading the Dataset

from datasets import load_dataset

ds = load_dataset(
    "prithivMLmods/OpenDetection-15K-Dense-v1.0",
    split="train"
)

Example Usage

from datasets import load_dataset
import matplotlib.pyplot as plt

ds = load_dataset(
    "prithivMLmods/OpenDetection-15K-Dense-v1.0",
    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()
