pub fn canny_derivative(

dy: &dyn ToInputArray,
edges: &mut dyn ToOutputArray,
threshold1: f64,
threshold2: f64,
l2gradient: bool

\overload
Finds edges in an image using the Canny algorithm with custom image gradient.
Parameters
- dx: 16-bit x derivative of input image (CV_16SC1 or CV_16SC3).
- dy: 16-bit y derivative of input image (same type as dx).
- edges: output edge map; single channels 8-bit image, which has the same size as image .
- threshold1: first threshold for the hysteresis procedure.
- threshold2: second threshold for the hysteresis procedure.
- L2gradient: a flag, indicating whether a more accurate norm should be used to calculate the image gradient magnitude ( L2gradient=true ), or whether the default norm is enough ( L2gradient=false ).
C++ default parameters
- l2gradient: false
