If nonzero, indicates that the raising of the Changed event has been suspended. This value is incremented when SuspendChangedEvent is called and decremented when ResumeAndRaiseChangedEvent is called.

If true, the serializable state of this object has changed since the last time it was serialized.

When hysteresis thresholding, a non-surviving pel will be output as this grey level. A pel in the EdgeMagnitudeImage will not survive if it is neither >= HysteresisThresholdHigh, nor >= HysteresisThresholdLow and 8-connected to a surviving pel.

When hysteresis thresholding, a surviving pel will be output as this grey level. A pel in the EdgeMagnitudeImage will survive if it is either >= HysteresisThresholdHigh, or >= HysteresisThresholdLow and 8-connected to a surviving pel.

If PostProcessMode is cogSobelEdgePostProcessModeHysteresisThreshold, then hysteresis thresholding will be run on the Sobel magnitude image using this as the magnitude level at or above which edges are never discarded.

If PostProcessMode is cogSobelEdgePostProcessModeHysteresisThreshold, then hysteresis thresholding will be run on the Sobel magnitude image using this as the magnitude level below which edges are always discarded.

Each magnitude image pixel value is set equal to the Sobel-computed grey value difference at the corresponding location multiplied by this scaling factor.

If PostProcessMode is cogSobelEdgePostProcessModePeakDetect, then whole-pixel peak detection will be run on the Sobel angle and magnitude images using this as the minimum Sobel magnitude. Edges with magnitude less than this will be discarded.

What, if any, post-processing to perform after Sobel.
