Dataset Annotation

AI-assisted dataset creation for training custom detection models. Supports three annotation methods with COCO format export.

What You Get

• BBox annotation, draw bounding boxes, AI auto-suggests
• SAM2 annotation, click to segment, get pixel-perfect masks
• DINOv3 annotation, click a patch, find similar objects across frames via visual grounding
• Object tracking, annotate keyframes, DINOv3 interpolates across the video
• COCO export, standard images[], annotations[], categories[] format
• Kaggle/HuggingFace upload, push datasets directly to platforms

Annotation Loop

1. Feed frames from clips → auto-detect objects
2. Human reviews → corrects bboxes, adds labels
3. Save as COCO dataset
4. Train improved model
5. Repeat with better auto-detection
