Detects edges in the incoming image
Algorithms:
Canny edge detection.
- sigma:
Standard deviation of gaussian kernel (default 1.0)
Find edges using the Laplace operator.
- kernel size:
Kernel size of the discrete Laplacian operator
Find edges using the Prewitt transform as one of, or combination of horizontal and vertical prewitt convolutions
- horizontal/vertical:
Select orientation for transform, if both then mean square of both will be used
Find edges using Robert’s cross operator.
- positive/negative diagonal:
Select orientation for transform
Find edges using the Scharr transform as one of, or combination of horizontal and vertical prewitt convolutions.
The Scharr operator has a better rotation invariance than other edge filters such as the Sobel or the Prewitt operators
- horizontal/vertical:
Select orientation for transform, if both then mean square of both will be used
Find edges using the Sobel transform as one of, or combination of horizontal and vertical prewitt convolutions.
- horizontal/vertical:
Select orientation for transform, if both then mean square of both will be used
