Vision Quality Control
We built a computer vision defect detection pipeline using YOLO with active learning for a manufacturing line. The system inspects products in real-time, flags defects, and continuously improves through operator feedback on edge cases.

What We Built
Key Features
YOLO-Based Defect Detection
State-of-the-art object detection model trained to identify surface defects, cracks, and anomalies in real time.
Active Learning Feedback Loop
Operators flag edge cases that automatically feed back into training, continuously improving model accuracy.
Real-Time Line-Speed Inspection
Sub-200ms inference per frame keeping pace with production line speeds without creating bottlenecks.
Defect Classification Dashboard
Visual analytics showing defect types, frequencies, trends, and production line performance over time.
Operator Review Interface
Intuitive UI for quality inspectors to review flagged items, confirm or override detections, and add annotations.
MES System Integration
API-based connection with Manufacturing Execution Systems for automated quality reporting and traceability.
The Challenge
Problems We Solved
- Achieving sub-200ms inference time
- Handling varied lighting conditions
- Building a training pipeline from limited initial data
The Outcome
Results Achieved
- 97.3% detection accuracy
- Under 200ms inference per frame
- 50% reduction in manual inspection costs
