Annotation types

Facial recognition annotation includes bounding boxes for face detection, landmarks for key feature mapping, segmentation for pixel-level classification, 3D annotation for depth analysis, occlusion detection for hidden faces, and emotion labeling for expression recognition.

Bounding Box for Face Detection

Bounding box annotation for object detection in security helps AI systems identify and track objects such as people, vehicles, or suspicious items within surveillance footage. By drawing precise rectangular boxes around objects, security systems can enhance threat detection, automate monitoring, and improve response times.

Segmentation for detecting faces

Accurately segment and detect faces using advanced AI-powered image processing. Ideal for facial recognition, security, and identity verification applications.

Facial Recognition AI FAQs

What facial recognition data can Unitlab AI annotate?

Unitlab supports face images, video, multiview captures, text, documents, and structured properties for governed identity-data workflows.

Which annotation types support face and landmark models?

Teams can use face boxes, keypoints and landmarks, polygons, segmentation, classifications, properties, and relations.

Can faces be tracked across video frames?

Yes. Video workflows support frame-accurate face tracking, keyframes, temporal labels, interpolation, and review.

How are identity attributes and findings organized?

Ontologies, controlled properties, classifications, and relations help teams keep face and identity labels consistent across datasets.

Can image quality and dataset balance be reviewed?

Data curation workflows help teams search, filter, deduplicate, balance, version, and select samples before annotation.

Does Unitlab support AI-assisted face annotation?

Built-in or custom models can pre-label supported visual data, with reviewers validating and correcting predictions.

How is facial annotation quality governed?

Instructions, reviewer roles, issues, rework, approvals, and annotation history support traceable quality control.

Can sensitive identity data stay on-premises?

Yes. On-premises deployment is available for organizations that need identity data, models, and workflows inside controlled infrastructure.

Who is responsible for consent and lawful use?

Customers remain responsible for obtaining appropriate rights, consent, and legal authority for facial recognition data and its intended use.
