EThresholdMode Enum

The various modes for thresholding that are supported by Open eVision.

Namespace: Euresys::Open_eVision

EThresholdMode_Absolute

Reserved value. For absolute thresholding, use the threshold value itself, cast to EThresholdMode.

EThresholdMode_Relative

Relative threshold; determines the required threshold level so that a given fraction of the image pixels lie below it.

EThresholdMode_MinResidue

Selects a threshold value such that the quadratic difference between the source and thresholded image is minimized.

EThresholdMode_MaxEntropy

Selects a threshold value such that the entropy (i.e. the amount of information) of the resulting thresholded image is maximized.

EThresholdMode_Isodata

Selects a threshold value that lies halfway between the average dark gray value (i.e. gray levels below the threshold) and average light gray values (i.e. gray levels above the threshold).
