A breakthrough AI project by Saiwa Inc. and AI-Innovate to automate surface defect detection on white and black paper with real-time precision and cost-saving benefits.
Challenge
Maintaining high-quality standards in paper manufacturing is no easy feat—especially when it comes to detecting subtle surface defects. Our client needed a solution that could accurately detect flaws in both white and black paper, two materials with vastly different visual properties.

Our Solution
In collaboration with AI-Innovate, we developed an AI-powered defect detection system as part of our Anomaly Detection service. This cutting-edge solution combines deep learning with smart preprocessing to localize and classify paper surface defects in real-time.
Detection on White Paper
We used advanced machine learning models to detect:
Cracks
Frost marks
Mold oscillations
Longitudinal irregularities
Our custom-built SegDecNet model—a two-stage architecture for segmentation and classification—enabled precise detection.
Detection on Black Paper
Detecting defects on black paper is inherently more difficult due to low contrast. To overcome this, we used our proprietary LLCC contrast enhancement algorithm, significantly improving visibility.
Key Technical Highlights
Image Tiling:
Images split into 1024×1024 px tiles for better accuracy and performance
Smart Labeling:
Using Saiwa Annotation Services, we reduced manual labeling while maximizing data quality
Dual-Track Training:
Separate AI models trained for white and black paper to address their unique characteristics
High-Speed Inference:
Models converted to ONNX & TensorRT for GPU-accelerated real-time performance
Results
Automated Quality Assurance:
Significantly reduced manual inspection workload
Real-Time Visualization:
Easy-to-use UI for quick defect review and decision-making
Cost Savings:
Reduced production downtime and material waste
