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 accepted U8 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
