What is a Keypoints Template and how is it useful?
Adding a template acts as a guideline for annotators that they can look at to get a better understanding of the labeling requirements. You can define the no. of points (nodes), how those points connect (segments) and even name them if needed. The annotators can easily refer to the template with a single click while they are annotating the dataset. The template will not only guide the annotators on the labeling requirements but also enforce them. This is particularly handy with KeyPoints as we need to ensure that the same no. of points are marked per annotation. KeyPoints templates are currently in beta.
How do I add one?
Templates are linked to a category, so you need to add a category before you can add a template. Please follow the below steps to add a Keypoints template:
Navigate to the categories page and add a category with category type Keypoints
Edit the category you just added and click on add template
Drag an image and drop in the box shown on screen
You can now continue with adding the nodes and segments per your requirement
Click on the submit button when you are done and your template is ready
How to use the template?
Once a template has been created, it can be easily added to a dataset while creating it. Please see the below example to understand
Navigate to the dataset page and click on add
After filling in the name and description (description is an optional field), select the category type as Keypoints.
Now you will see a field for template and from the dropdown you can create the template you just created
Your template is now ready and your annotators can see by clicking on the “Show Template” button on the annotation page
