Monitoring annotation complexity

When annotating an asset, you can check the current complexity of the annotation work using the counter located in the bottom-right corner of the Job viewer. This counter sums up all annotation tasks that have been completed so far and lists them broken down into categories.

How the tasks are calculated

For most asset types, the calculation is a simple addition of annotations added in all the jobs and sub-jobs. For example, for a bbox with several optional sub-jobs, the count increases once for the bbox and once for each or the sub-jobs that the labeler decides to fill out.

Calculations for some specific project types and job types require additional explanation:

  • For multiple-choice classification jobs, the annotation count increases by 1 per job/subjob, regardless of the number of classes selected.
  • For video assets, only key frames are counted as separate annotations. This means that when propagation is set to "on", annotation count does not increase unless you make a change in one of the frames. For example, in a 100-frame video, on frame #1 you annotate an object with propagation on: object gets propagated to all the 100 frames but the annotation count increases only by 1. Then, on frame #50, you move the object or make a change in the subscription sub-job: annotation count increases by 1 and the total is now 2.
