Practical solutions to improve the labeling accuracy of AI training data
Annotation quality can be systematically improved using Annot8:
- Visual Calibration Tool200% magnifier function ensures pixel-level accuracy, especially for framing small targets.
- Multi-level checking mechanism: Support annotation preview mode to globally check annotation consistency in a thumbnail matrix.
- Standardized workpiece flow: Suggested annotation process: initial review → batch annotation → sampling review → final export, forming a quality closed loop
- metadata management: Ensure semantic consistency through a standardized label naming system (e.g., using the coco_ format)
Specific implementation:
- Creating documentation for markup specifications
- Two-person labeling-cross-validation for complex samples
- Automated checking of coordinate validity with CSV exported scripts
- Periodic sample manual review of 3-5% labeling results
