CogBlobSegmentationParams.SoftFixedThresholdLow Property

CogBlobSegmentationParams SoftFixedThresholdLow Property

Cognex VisionPro

Pixel values below the low threshold are background (weight 0) or full-weight blob (weight 1.0) depending on the Polarity. Values between the low and high thresholds are considered fractional blob (weight between 0 and 1, exclusive). See Softness.

Exceptions

Exception	Condition
[System.ArgumentException]	The supplied value is less than 0 or greater than 65534.

Remarks

The low threshold for soft fixed segmentation. Pixel values that are less than the low threshold are assigned a blob weight of 0 when Polarity indicates light blobs. Pixel values that are less than the low threshold are assigned a blob weight of 1 when Polarity indicates dark blobs.

The low threshold must be less than the high threshold. If a value is supplied such that this requirement is not met, the other threshold is adjusted.
