Polygon Annotation Services

When objects lack clean rectangular bounds, polygon annotation captures true geometry for segmentation and instance models. We label shelf planes, lane boundaries, roof footprints, tissue regions, and industrial defects with written playbooks for edge ambiguity.

Guidelines for messy real-world boundaries

Rules for partial objects, shared boundaries, anti-aliasing, and zoom levels so polygon vertices stay consistent across annotators and capture conditions.

Instance vs semantic workflows

Separate instance IDs for overlapping objects, semantic regions for scene classes, and hybrid projects mixing boxes with fine polygons.

Domain-trained polygon teams

Retail planograms, geospatial tiles, medical imaging, and AV lane graphs staffed with reviewers who understand domain edge cases.

Quality at the vertex level

Multi-tier review, boundary distance audits, and golden polygons for classes with high error cost in production.

Secure delivery at scale

Million-vertex programs with encrypted pipelines and flexible exports to your MLOps stack.
