CogCNLSearchPattern IgnorePolarity Property

Cognex VisionPro

If true, pattern polarity is ignored. If false, only patterns with polarity matching the trained pattern will be found. Only applies to linear search. Linear CNLPAS never ignores polarity. NonLinear CNLPAS always ignores polarity.

Remarks

If true, pattern polarity is ignored. If false, only patterns with polarity matching the trained pattern will be found. This property only applies to Linear Search. Linear CNLPAS always considers polarity while Nonlinear CNLPAS always ignores polarity.

In general, ignoring polarity increases potential image confusion. Unless you know that your application will need to recognize inverted polarity

Default Value: False
