sharpai 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
