public:
void SetSegmentationHardDynamicThreshold(
	int tailLow, 
	int tailHigh, 
	CogBlobSegmentationPolarityConstants polarity
)

Parameters

tailLow: Type: System Int32
The percentage of low tail pixels to discard before computing the hard relative threshold.

tailHigh: Type: System Int32
The percentage of high tail pixels to discard before computing the hard relative threshold.

polarity: Type: Cognex.VisionPro.Blob CogBlobSegmentationPolarityConstants
Specify DarkBlobs for dark blobs on a light background or LightBlobs for light blobs on a dark background.

Exceptions

Exception	Condition
ArgumentException	tailLow or tailHigh is less than 0 or greater than 100.
ArgumentException	tailLow plus tailHigh is greater than 100.
ArgumentException	polarity is neither DarkBlobs nor LightBlobs.

Remarks

Sets the segmentation Mode to HardDynamicThreshold and sets TailLow, TailHigh, HardRelativeThreshold and Polarity to the values supplied.

This function suspends event delivery, then sets the public properties of CogBlobSegmentationParams with the supplied values. A single event that includes all of the affected functional area is typically generated.
