Pose Estimation Datasets Overview
Supported Dataset Formats
Ultralytics YOLO format
The dataset label format used for training YOLO pose models is as follows:
- One text file per image: Each image in the dataset has a corresponding text file with the same name as the image file and the ".txt" extension.
- One row per object: Each row in the text file corresponds to one object instance in the image.
- Object information per row: Each row contains the following information about the object instance:
- Object class index: An integer representing the class of the object (e.g., 0 for person, 1 for car, etc.).
- Object center coordinates: The x and y coordinates of the center of the object, normalized to be between 0 and 1.
- Object width and height: The width and height of the object, normalized to be between 0 and 1.
- Object keypoint coordinates: The keypoints of the object, normalized to be between 0 and 1.
Here is an example of the label format for pose estimation task:
Format with Dim = 2
<class-index> <x> <y> <width> <height> <px1> <py1> <px2> <py2> ... <pxn> <pyn>
Format with Dim = 3
<class-index> <x> <y> <width> <height> <px1> <py1> <p1-visibility> <px2> <py2> <p2-visibility> <pxn> <pyn> <p2-visibility>
In this format, <class-index> is the index of the class for the object,<x> <y> <width> <height> are coordinates of bounding box, and <px1> <py1> <px2> <py2> ... <pxn> <pyn> are the pixel coordinates of the keypoints. The coordinates are separated by spaces.
Dataset YAML format
The Ultralytics framework uses a YAML file format to define the dataset and model configuration for training Detection Models. Here is an example of the YAML format used for defining a detection dataset:
# Train/val/test sets as 1) dir: path/to/imgs, 2) file: path/to/imgs.txt, or 3) list: [path/to/imgs1, path/to/imgs2, ..]
path: ../datasets/coco8-pose # dataset root dir
train: images/train # train images (relative to 'path') 4 images
val: images/val # val images (relative to 'path') 4 images
test: # test images (optional)
# Keypoints
kpt_shape: [17, 3] # number of keypoints, number of dims (2 for x,y or 3 for x,y,visible)
flip_idx: [0, 2, 1, 4, 3, 6, 5, 8, 7, 10, 9, 12, 11, 14, 13, 16, 15]
# Classes dictionary
names:
0: person
The train and val fields specify the paths to the directories containing the training and validation images, respectively.
names is a dictionary of class names. The order of the names should match the order of the object class indices in the YOLO dataset files.
(Optional) if the points are symmetric then need flip_idx, like left-right side of human or face. For example if we assume five keypoints of facial landmark: [left eye, right eye, nose, left mouth, right mouth], and the original index is [0, 1, 2, 3, 4], then flip_idx is [1, 0, 2, 4, 3] (just exchange the left-right index, i.e. 0-1 and 3-4, and do not modify others like nose in this example).
Usage
!!! Example
=== "Python"
```py
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="coco8-pose.yaml", epochs=100, imgsz=640)
```
=== "CLI"

Instance Segmentation Datasets Overview
Supported Dataset Formats
Ultralytics YOLO format
The dataset label format used for training YOLO segmentation models is as follows:
- One text file per image: Each image in the dataset has a corresponding text file with the same name as the image file and the ".txt" extension.
- One row per object: Each row in the text file corresponds to one object instance in the image.
- Object information per row: Each row contains the following information about the object instance:
- Object class index: An integer representing the class of the object (e.g., 0 for person, 1 for car, etc.).
- Object bounding coordinates: The bounding coordinates around the mask area, normalized to be between 0 and 1.
The format for a single row in the segmentation dataset file is as follows:
<class-index> <x1> <y1> <x2> <y2> ... <xn> <yn>
In this format, <class-index> is the index of the class for the object, and <x1> <y1> <x2> <y2> ... <xn> <yn> are the bounding coordinates of the object's segmentation mask. The coordinates are separated by spaces.
Here is an example of the YOLO dataset format for a single image with two objects made up of a 3-point segment and a 5-point segment.

- The length of each row does **not** have to be equal.
- Each segmentation label must have a **minimum of 3 xy points**: `<class-index> <x1> <y1> <x2> <y2> <x3> <y3>`
Dataset YAML format
The Ultralytics framework uses a YAML file format to define the dataset and model configuration for training Detection Models. Here is an example of the YAML format used for defining a detection dataset:
# Train/val/test sets as 1) dir: path/to/imgs, 2) file: path/to/imgs.txt, or 3) list: [path/to/imgs1, path/to/imgs2, ..]
path: ../datasets/coco8-seg # dataset root dir
train: images/train # train images (relative to 'path') 4 images
val: images/val # val images (relative to 'path') 4 images
test: # test images (optional)
# Classes (80 COCO classes)
names:
0: person
1: bicycle
2: car
# ...
77: teddy bear
78: hair drier
79: toothbrush
The train and val fields specify the paths to the directories containing the training and validation images, respectively.
names is a dictionary of class names. The order of the names should match the order of the object class indices in the YOLO dataset files.
Usage
!!! Example
=== "Python"
```py
from ultralytics import YOLO
# Load a model
model = YOLO("yolov8n-seg.pt") # load a pretrained model (recommended for training)
# Train the model
results = model.train(data="coco8-seg.yaml", epochs=100, imgsz=640)
```
=== "CLI"
```py
# Start training from a pretrained *.pt model
yolo detect train data=coco8-seg.yaml model=yolov8n-seg.pt epochs=100 imgsz=640
```

Analytics using Ultralytics YOLOv8
Introduction
This guide provides a comprehensive overview of three fundamental types of data visualizations: line graphs, bar plots, and pie charts. Each section includes step-by-step instructions and code snippets on how to create these visualizations using Python.
Visual Samples
| Line Graph | Bar Plot | Pie Chart |
|---|---|---|
Why Graphs are Important
- Line graphs are ideal for tracking changes over short and long periods and for comparing changes for multiple groups over the same period.
- Bar plots, on the other hand, are suitable for comparing quantities across different categories and showing relationships between a category and its numerical value.
- Lastly, pie charts are effective for illustrating proportions among categories and showing parts of a whole.
