Hand Keypoints Dataset
EinfĂŒhrung
The hand-keypoints dataset contains 26,768 images of hands annotated with keypoints, making it suitable for training models like Ultralytics YOLO for pose estimation tasks. The annotations were generated using the Google MediaPipe library, ensuring high accuracy and consistency, and the dataset is compatible Ultralytics YOLO11 formats.
Hand Landmarks
KeyPoints
The dataset includes keypoints for hand detection. The keypoints are annotated as follows:
- Wrist
- Thumb (4 points)
- Index finger (4 points)
- Middle finger (4 points)
- Ring finger (4 points)
- Little finger (4 points)
Each hand has a total of 21 keypoints.
Hauptmerkmale
- Large Dataset: 26,768 images with hand keypoint annotations.
- YOLO11 Compatibility: Ready for use with YOLO11 models.
- 21 Keypoints: Detailed hand pose representation.
Struktur des Datensatzes
The hand keypoint dataset is split into two subsets:
- Train: This subset contains 18,776 images from the hand keypoints dataset, annotated for training pose estimation models.
- Val: This subset contains 7992 images that can be used for validation purposes during model training.
Anwendungen
Hand keypoints can be used for gesture recognition, AR/VR controls, robotic manipulation, and hand movement analysis in healthcare. They can be also applied in animation for motion capture and biometric authentication systems for security.
Datensatz YAML
A YAML (Yet Another Markup Language) file is used to define the dataset configuration. It contains information about the dataset's paths, classes, and other relevant information. In the case of the Hand Keypoints dataset, the hand-keypoints.yaml

Beispielbilder und Anmerkungen
The Hand keypoints dataset contains a diverse set of images with human hands annotated with keypoints. Here are some examples of images from the dataset, along with their corresponding annotations:
- Mosaikbild: Dieses Bild zeigt einen Trainingsstapel, der aus Mosaikbildern des Datensatzes besteht. Beim Mosaikieren werden mehrere Bilder zu einem einzigen Bild zusammengefĂŒgt, um die Vielfalt der Objekte und Szenen in jedem Trainingsstapel zu erhöhen. Dadurch wird die FĂ€higkeit des Modells verbessert, sich auf verschiedene ObjektgröĂen, SeitenverhĂ€ltnisse und Kontexte einzustellen.
The example showcases the variety and complexity of the images in the Hand Keypoints dataset and the benefits of using mosaicing during the training process.
