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. | |

Find edges based on absolute intensities in the image. More... | |
int | IntensitySubPixel = 1 |
Like EdgeSearchMode.Intensity, but with sub pixel accuracy. | |

Determines the algorithm for finding an edge.
|
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.
|
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.
