## Dataset Structure

The HomeObjects-3K dataset is organized into the following subsets:

- **Training Set**: Comprises 2,285 annotated images featuring objects such as sofas, chairs, tables, lamps, and more.
- **Validation Set**: Includes 404 annotated images designated for evaluating model performance.

Each image is labeled using bounding boxes aligned with the [Ultralytics YOLO](../detect/index.md/#what-is-the-ultralytics-yolo-dataset-format-and-how-to-structure-it) format. The diversity of indoor lighting, object scale, and orientations makes it robust for real-world deployment scenarios.

## Object Classes

The dataset supports 12 everyday object categories, covering furniture, electronics, and decorative items. These classes are chosen to reflect common items encountered in indoor domestic environments and support vision tasks like [object detection](../../tasks/detect.md) and [object tracking](../../modes/track.md).

## Applications

HomeObjects-3K enables a wide spectrum of applications in indoor computer vision, spanning both research and real-world product development:

- **Indoor object detection**: Use models like [Ultralytics YOLO26](../../models/yolo26.md) to find and locate common home items like beds, chairs, lamps, and laptops in images. This helps with real-time understanding of indoor scenes.

- **Scene layout parsing**: In robotics and smart home systems, this helps devices understand how rooms are arranged, where objects like doors, windows, and furniture are, so they can navigate safely and interact with their environment properly.

- **AR applications**: Power [object recognition](http://ultralytics.com/glossary/image-recognition) features in apps that use augmented reality. For example, detect TVs or wardrobes and show extra information or effects on them.

- **Education and research**: Support learning and academic projects by giving students and researchers a ready-to-use dataset for practicing indoor object detection with real-world examples.

- **Home inventory and asset tracking**: Automatically detect and list home items in photos or videos, useful for managing belongings, organizing spaces, or visualizing furniture in real estate.
