Creating the skeleton
Initial skeleton setup
Unlike other CVAT objects, to start annotating using skeletons, first of all you need to setup a skeleton. You can do that in the label configurator during creating a task/project, or later in created instances.
So, start by clicking
Setup skeleton option:
Below the regular label form where you need to add a name, and setup attributes if necessary, you will see a drawing area with some buttons aside:
- PUT AN IMAGE AS A BACKGROUND - is a helpful feature you can use to draw a skeleton template easier, seeing an example - object you need to annotate in the future.
- PUT NEW SKELETON POINTS - is activated by default. It is a mode where you can add new skeleton points clicking the drawing area.
- DRAW AN EDGE BETWEEN TWO POINTS - in this mode you can add an edge, clicking any two points, which are not joined yet.
- REMOVE A DRAWN SKELETON POINTS - in this mode clicking a point will remove the point and all attached edges. You can also remove an edge only, it will be highligted as red on hover.
- DOWNLOAD DRAWN TEMPLATE AS AN .SVG - you can download setup configuration to use it in future
- UPLOAD A TEMPLATE FROM AN .SVG FILE - you can upload previously downloaded configuration
Let’s draw an exampe skeleton - star. After the skeleton is drawn, you can setup each its point.
Just hover the point, do right mouse click and click
Here you can setup a point name, its color and attributes if necessary like for a regular CVAT label:
Done button to finish editing the point. Press
Continue button to save the skeleton.
Continue creating a task/project in a regular way.
For an existing task/project you are not allowed to change a skeleton configuration for now.
You can copy/insert skeletons configuration using
Raw tab of the label configurator.
