Multimodal Labeling

Expert-level 2D and 3D annotation. No data limits.

Create 2D and 3D multi-sensor labels for classification, detection, and segmentation. Adjust bounding boxes and segmentation masks directly in FiftyOne. No limit on the amount of data labeled.

Annotate 2D and 3D scenes

• Draw 3D cuboids and polylines on point clouds, depth maps, and 3D scenes.
• Create segmentation masks, classifications, and bounding boxes for 2D image types.
• Ease 3D labeling of dense image scenes or sparse point clouds by viewing them alongside 2D images and orthographic camera projections.

ML Research

Auto-labeling rivals human performance

The latest paper from our ML researchers, Auto-Labeling Data for Object Detection, benchmarks auto-labeling against human annotation. We reveal how foundation models can deliver labels at near-human accuracy, while reducing annotation costs by up to 100,000×.
