Multimodal & vision labeling

Precise annotation for images and video.

Pixel-accurate annotation by trained labelers, with domain experts in the loop for anything specialized.

What it is

Dense, consistent labels across every frame.

Vision and multimodal models are only as good as their labels. We annotate images, video, and multi-view media to your spec and schema.

  • Bounding boxes and polygons
  • Semantic and instance segmentation
  • Keypoints and pose
  • Video object tracking and event tagging
  • Dense captioning and visual Q&A

Who it’s for

Built for teams training models that see.

Detection & segmentation

Boxes, polygons, and semantic and instance masks for perception models.

Pose & tracking

Keypoints, pose, and object tracking across video frames and multi-view captures.

Multimodal models

Dense captions and visual Q&A that pair images and video with language.

How it works

Labeled, reviewed, delivered in your schema.

Scope

We agree label types, ontology, media, and format with you on a short scoping call.

Annotate

Trained labelers annotate to written guidelines, with domain experts in the loop for specialized content.

Consensus QA

Multi-pass consensus review checks every label before it ships to your storage.

FAQ

Vision & multimodal labeling: common questions

What vision annotation types do you support?

Bounding boxes and polygons, semantic and instance segmentation, keypoints and pose, video object tracking and event tagging, and dense captioning and visual Q&A.

Which formats do you deliver?

COCO, YOLO, JSON, or a custom format, in your schema.

Do you label video and multi-view data?

Yes. We annotate images, video, and multi-view media, including object tracking and event tagging across frames.

How is quality controlled?

Every label goes through multi-pass consensus review before delivery.

Who does the labeling?

Trained labelers, with domain experts in the loop for anything specialized.

Where is data delivered?

To your storage, in your schema — for example S3, a private Hugging Face repo, or your own bucket.
