Techniques

Every image labeling technique your model needs.

We match the annotation type to what your model actually has to learn — not a one-size-fits-all label set.

Detection

Bounding Box Annotation

Fast, precise rectangular boxes for object detection — vehicles, products, people, defects, and more.

Shape

Polygon Annotation

Tight, irregular-shape outlines for objects that boxes can't capture accurately, from packaging to anatomy.

Pixel-level

Semantic Segmentation

Every pixel classified into a category — roads, sky, tissue, terrain — for scene-understanding models.

Pixel-level

Instance Segmentation

Pixel masks that separate individual object instances, even when they overlap or touch.

Structure

Keypoint & Skeleton Annotation

Joint and landmark labeling for pose estimation, motion capture, and biomechanical analysis.

Line

Polyline Annotation

Line-based labeling for lane markings, cables, edges, and other linear features.

Where it's used

Industries running on our image annotation.

Retail & e-commerce

Product recognition, shelf and planogram compliance, visual search catalogs.

Healthcare & medical imaging

Anatomical structure and anomaly labeling for diagnostic and research models.

Security & surveillance

Person and object detection across static and multi-camera imagery.

Common questions

FAQ

What image formats do you support for annotation?

We work with JPEG, PNG, TIFF, DICOM for medical imagery, and most common raster formats, delivered in COCO, Pascal VOC, YOLO, or your custom JSON schema.

How accurate is your image annotation?

Every asset passes through annotator, reviewer, and senior QA sign-off, with accuracy tracked against your acceptance thresholds throughout the project.

Can you handle medical or sensitive imagery?

Yes. Medical and other sensitive image sets are handled under NDA with restricted access controls — see our Medical Annotation page for specifics.
