# Tiger-Pose Dataset |
|
|
|
## Introduction |
|
|
|
[Ultralytics](https://ultralytics.com) introduces the Tiger-Pose dataset, a versatile collection designed for pose estimation tasks. This dataset comprises 263 images sourced from a [YouTube Video](https://www.youtube.com/watch?v=MIBAT6BGE6U&pp=ygUbVGlnZXIgd2Fsa2luZyByZWZlcmVuY2UubXA0), with 210 images allocated for training and 53 for validation. It serves as an excellent resource for testing and troubleshooting pose estimation algorithm. |
|
|
|
Despite its manageable size of 210 images, tiger-pose dataset offers diversity, making it suitable for assessing training pipelines, identifying potential errors, and serving as a valuable preliminary step before working with larger datasets for pose estimation. |
|
|
|
This dataset is intended for use with [Ultralytics HUB](https://hub.ultralytics.com) and [YOLOv8](https://github.com/ultralytics/ultralytics). |

## Dataset YAML |
|
|
|
A YAML (Yet Another Markup Language) file serves as the means to specify the configuration details of a dataset. It encompasses crucial data such as file paths, class definitions, and other pertinent information. Specifically, for the `tiger-pose.yaml` file, you can check [Ultralytics Tiger-Pose Dataset Configuration File](https://github.com/ultralytics/ultralytics/blob/main/ultralytics/cfg/datasets/tiger-pose.yaml). |
|
|
|
!!! Example "ultralytics/cfg/datasets/tiger-pose.yaml" |
|
|
|
```yaml |
|
--8<-- "ultralytics/cfg/datasets/tiger-pose.yaml" |
|
``` |
|
|
|
## Usage |
|
|
|
To train a YOLOv8n-pose model on the Tiger-Pose dataset for 100 epochs with an image size of 640, you can use the following code snippets. For a comprehensive list of available arguments, refer to the model [Training](../../modes/train.md) page. |
|
|
|
!!! Example "Train Example" |
|
|
|
=== "Python" |
|
|
|
```python |
|
from ultralytics import YOLO |
|
|
|
# Load a model |
|
model = YOLO("yolov8n-pose.pt") # load a pretrained model (recommended for training) |
|
|
|
# Train the model |
|
results = model.train(data="tiger-pose.yaml", epochs=100, imgsz=640) |
|
``` |
|
|
|
=== "CLI" |
|
|
|
```bash |
|
# Start training from a pretrained *.pt model |
|
yolo task=pose mode=train data=tiger-pose.yaml model=yolov8n.pt epochs=100 imgsz=640 |
|
``` |
|
|
|
## Sample Images and Annotations |
|
|
|
Here are some examples of images from the Tiger-Pose dataset, along with their corresponding annotations: |

|
|
|
- **Mosaiced Image**: This image demonstrates a training batch composed of mosaiced dataset images. Mosaicing is a technique used during training that combines multiple images into a single image to increase the variety of objects and scenes within each training batch. This helps improve the model's ability to generalize to different object sizes, aspect ratios, and contexts. |
|
|
|
The example showcases the variety and complexity of the images in the Tiger-Pose dataset and the benefits of using mosaicing during the training process. |

## Inference Example |
|
|
|
!!! Example "Inference Example" |
|
|
|
=== "Python" |
|
|
|
```python |
|
from ultralytics import YOLO |
|
|
|
# Load a model |
|
model = YOLO("path/to/best.pt") # load a tiger-pose trained model |
|
|
|
# Run inference |
|
results = model.predict(source="https://youtu.be/MIBAT6BGE6U", show=True) |
|
``` |
|
|
|
=== "CLI" |
|
|
|
```bash |
|
# Run inference using a tiger-pose trained model |
|
yolo task=pose mode=predict source="https://youtu.be/MIBAT6BGE6U" show=True model="path/to/best.pt" |
|
``` |
