Parameters

hysteresisThresholdLow: Type: System Int32
If PostProcessMode is HysteresisThreshold, then hysteresis thresholding will be run on the edge magnitude image using this as the magnitude level below which edges are always discarded.

hysteresisThresholdHigh: Type: System Int32
If PostProcessMode is HysteresisThreshold, then hysteresis thresholding will be run on the edge magnitude image using this as the magnitude level at or above which edges are never discarded.

Events

Exceptions

Exception	Condition
ArgumentException	One of the threshold values was less than 0 or greater than 255.
ArgumentException	HysteresisThreholdHigh is less than hysteresisThresholdLow.

Remarks
