• Strategic selection between detection, classification, and segmentation tasks.

Developing Defect Detection Models

• Curation and preparation of annotated datasets.
• Training effective defect classifiers and segmenters.
• Model performance evaluation using metrics such as precision, recall, and F1-score.

Industrial Deployment Strategies

• Hardware assessment: GPUs, edge devices, and industrial PCs.
• Designing real-time inspection pipeline architecture.
• System integration with PLCs and broader factory automation infrastructure.

Performance Optimization and Maintenance

• Adapting to variable lighting and shifting production conditions.
