2.15.4 Optimizing Boolean Expressions and Inspection Criterion Values
Inspection criterion values are optimized based on the visual check result information
registered for each inspection window of model images. Optimization can reduce
missing/excessive detection of errors.

The logic expression allows a comprehensive evaluation for judgment through combination of the
inspection result judgments for individual fillet and electrode posture inspection items, which can
facilitate the reduction of false calls.
