Set up a project workflow

As a Project Admin, you can create a workflow to distribute accurate annotation instructions and steps to help your team save time.

To create a project workflow:

  1. In Workflow, click Create Workflow.
  2. To add a step, choose a class.
  3. Choose an attribute (optional).
  4. Choose the annotation tool from the drop-down menu.
  5. Select New Step to add more steps.
  6. To automate the workflow, check the Automatic class change box.
  7. To apply the workflow, check the Apply the workflow box.

Click and drag the reorder button to change the order of the steps.

Workflow automation

When you check the Automatic class change box, your workflow will be automated, which means that when an Annotator goes to the editor, the class and the tool of the first step will automatically be selected. When the Annotator finishes completing the first step, the class and the tool of the second step will automatically be selected, and so on.

Keypoint workflow

The keypoint workflow guides you to annotate the right parts of the image in the Vector Editor in the right sequence. The steps that are connected to each other will have their corresponding keypoints connected. This helps with projects where you need to use templates like annotating faces, hands, etc.

Example:

  • Step 1: Top-right corner of the dor
  • Step 2: Top-left corner of the door
  • Step 3: Bottom-left corner of the door
  • Step 4: Bottom right corner of the door

All the steps in a workflow belong to one group. In the case of the example above, all 4 keypoints will be part of Group 1. The other set of keypoints will belong to another group.
