Static Public Attributes
int	Contrast = 2
	Find edges based on the contrasts in the image (1st derivative of the gray values).
int	ContrastSubPixel = 3
	Like EdgeSearchMode.Contrast, but with sub pixel accuracy.
int	Intensity = 0
	Find edges based on absolute intensities in the image.
int	IntensitySubPixel = 1
	Like EdgeSearchMode.Intensity, but with sub pixel accuracy.
int	SecondDerivativeSubPixel = 4
	Find edges based on the 2nd derivative of the intensities with sub pixel accuracy.

Detailed Description

Determines the algorithm for finding an edge.

Member Data Documentation

Intensity

int Intensity = 0

static

Find edges based on absolute intensities in the image.

In this mode, the edge quality directly corresponds to the difference in intensity across the edge.

SecondDerivativeSubPixel

int SecondDerivativeSubPixel = 4

static

Find edges based on the 2nd derivative of the intensities with sub pixel accuracy.

Note that in this mode edge qualities are usually much lower than 10.
