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.
