Task duplication

Task duplication is a project workflow setting that allows you to create N tasks from a single image so that N different labelers can annotate the image N times.

Create a Project with Task Duplication

While creating a project, in the Multiple Labeling section, select Multiple Outputs and then select the number of "sibling tasks", i.e., the number of times a task will be duplicated.

Once you upload tasks to your project, you will notice N x the number of images uploaded to the project. Each distinct sibling task can be assigned to a different annotator. You can view all sibling tasks together using the "view sibling" task shortcut.
