Visual Quality Inspection
Automated visual quality control for manufacturing, using OpenCV/scikit-image feature extraction with scikit-learn classification.
Problem
Manual visual quality control on a manufacturing line is slow, inconsistent between inspectors, and doesn't scale.
Solution
OpenCV/scikit-image feature extraction combined with a scikit-learn classifier to automate defect detection directly from product images.
Overview
Manual visual QC on a production line doesn’t scale — it’s slow, and two inspectors rarely agree perfectly on borderline cases.
How it works
Product images are processed with OpenCV/scikit-image to extract visual features (edges, texture, color distribution), which feed a scikit-learn classifier trained to distinguish defective from acceptable units. The result is a consistent, repeatable pass/fail decision applied identically to every unit.
Result
Automated defect detection that removes inspector-to-inspector inconsistency and scales to line speed.
