# HockeyAI: A Multi-Class Ice Hockey Dataset for Object Detection
|
| 21 |
+
|
| 22 |
+
The **HockeyAI dataset** is an open-source dataset designed specifically for advancing computer vision research in ice hockey. With approximately **2,100 high-resolution frames** and detailed YOLO-format annotations, this dataset provides a rich foundation for tackling the challenges of object detection in fast-paced sports environments.
|
| 23 |
+
|
| 24 |
+
The dataset is ideal for researchers, developers, and practitioners seeking to improve object detection and tracking tasks in ice hockey or similar dynamic scenarios.
|
| 25 |
+
|

|
|
|
|
| 27 |
|
| 28 |
+
## Dataset Overview
|
| 29 |
+
|
| 30 |
+
The HockeyAI dataset includes frames extracted from **broadcasted Swedish Hockey League (SHL) games**. Each frame is manually annotated, ensuring high-quality labels for both dynamic objects (e.g., players, puck) and static rink elements (e.g., goalposts, center ice).
|
| 31 |
+
|
| 32 |
+
### Classes
|
| 33 |
+
The dataset includes annotations for the following seven classes:
|
| 34 |
+
- **centerIce**: Center circle on the rink
|
| 35 |
+
- **faceoff**: Faceoff dots
|
| 36 |
+
- **goal**: Goal frame
|
| 37 |
+
- **goaltender**: Goalkeeper
|
| 38 |
+
- **player**: Ice hockey players
|
| 39 |
+
- **puck**: The small, fast-moving object central to gameplay
|
| 40 |
+
- **referee**: Game officials
|
| 41 |
|
| 42 |
|
| 43 |

|
| 44 |
+
|
| 45 |
+
|
| 46 |
+
### Key Highlights:
|
| 47 |
+
- **Resolution**: 1920Γ1080 pixels
|
| 48 |
+
- **Frames**: ~2,100
|
| 49 |
+
- **Source**: Broadcasted SHL videos
|
| 50 |
+
- **Annotations**: YOLO format, reviewed iteratively for accuracy
|
| 51 |
+
- **Challenges Addressed**:
|
| 52 |
+
- Motion blur caused by fast camera movements
|
| 53 |
+
- Small object (puck) detection
|
| 54 |
+
- Crowded scenes with occlusions
|
| 55 |
+
|
| 56 |

+
## Applications
|
| 59 |
+
|
| 60 |
+
The dataset supports a wide range of applications, including but not limited to:
|
| 61 |
+
- **Player and Puck Tracking**: Enabling real-time tracking for tactical analysis.
|
| 62 |
+
- **Event Detection**: Detecting goals, penalties, and faceoffs to automate highlight generation.
|
| 63 |
+
- **Content Personalization**: Dynamically reframing videos to suit different screen sizes.
|
| 64 |
+
- **Sports Analytics**: Improving strategy evaluation and fan engagement.

+
## Pretrained Model
|
| 70 |
+
|
| 71 |
+
In addition to the dataset, a **YOLOv8 medium model** fine-tuned on the HockeyAI dataset is available. The model achieves high performance across all seven classes and serves as a benchmark for future research. You can access the model by dowloading the pt file under this repo.
|
| 72 |
+

+
## How to Use the Dataset
|
| 76 |
+
|
| 77 |
+
1. Download the dataset from [Hugging Face](https://huggingface.co/your-dataset-link).
|
| 78 |
+
2. The dataset is organized in the following structure:
|
| 79 |
+
HockeyAI/ βββ frames/ β βββ <Unique_ID>.jpg βββ annotations/ β βββ <Unique_ID>.txt
|
| 80 |
+
|
| 81 |
+
|
| 82 |
+
3. Each annotation file follows the YOLO format:
|
| 83 |
+
<class_id> <x_center> <y_center> <width> <height
|
| 84 |
+
|
| 85 |
+
|
| 86 |
+
All coordinates are normalized to the image dimensions.
|
| 87 |
+
|
| 88 |
+
4. Use the dataset with your favorite object detection framework, such as YOLOv8 or PyTorch-based solutions.
