Canny Edge Detection

Description

Uses a specialized edge detection method to accurately estimate the location of edges even under conditions of poor signal-to-noise ratios. Type : polymorphic.

 

Input parameters

 

Image Src : class, type acceptedΒ U8Β and I16.

Canny Parameters : cluster,

Lower Threshold : float, first threshold for the hysteresis procedure.
Higher Threshold : float, second threshold for the hysteresis procedure.
Kernel Size : integer, aperture size for the Sobel operator.
 L2 Gradient : boolean, a flag, indicating whether a more accurate L2 norm should be used to calculate the image gradient magnitude ( L2gradient=true ), or whether the default L1 norm is enough ( L2gradient=false ).

Output parameters

 

Image Dst : class

Examples
