Comprehensive Annotation Services

Expert labeling across all major data types and annotation formats

2D Bounding Box & Image Classification

Industry-standard rectangular annotations for object detection combined with whole-image categorization. Perfect for training YOLO, R-CNN, SSD detection models, and content moderation.

Tight-fitting boxes with precise coordinates (x, y, width, height) and categorical labels with confidence scores. Handle overlapping objects, partial occlusions, rotated bounding boxes, hierarchical taxonomies, multi-label classification for large-scale organization.

Polygon & Segmentation

Pixel-precise annotations for complex irregular shapes and boundaries. Essential for medical imaging, satellite imagery analysis, and autonomous driving perception applications.

Multi-point polygons with unlimited vertices for accurate object boundaries and edge detection. Supports instance segmentation for individual objects, semantic segmentation for pixel classification, and panoptic segmentation combining both approaches.

Keypoint & Landmark Annotation

Precise point marking for pose estimation, facial recognition, and skeletal tracking systems. Critical for fitness applications, AR filters, and advanced biometric systems.

Mark anatomical landmarks, joint positions, custom points with sub-pixel accuracy and precision. Supports skeletal connections, visibility flags for occluded points, and confidence scores for quality assessment and validation.
