Annotation Metrics and Spatiotemporal Comments in Voxel51

Voxel51 Annotation has introduced metrics and spatiotemporal comments to help teams better assess annotation workflows beyond simple sample-completion counts. The metrics dashboard tracks throughput, time spent, label additions, deletions, and modifications, as well as review outcomes such as approval and rejection rates, enabling analysis by annotator, workflow stage, dataset, or deployment. Separate measurements for Annotate and Review stages are generated by aggregating in-application event data, helping teams identify patterns such as increasing rejection rates or unusually long annotation times. The new spatiotemporal comments feature lets reviewers attach targeted feedback to specific image regions or video frames, providing annotators with clearer guidance for correcting individual labels.
