[−][src]Function opencv::imgproc::spatial_gradient

pub fn spatial_gradient(
    src: &dyn ToInputArray, 
    dx: &mut dyn ToOutputArray, 
    dy: &mut dyn ToOutputArray, 
    ksize: i32, 
    border_type: i32
) -> Result<()>

Calculates the first order image derivative in both x and y using a Sobel operator

Equivalent to calling:

ⓘThis example is not tested
Sobel( src, dx, CV_16SC1, 1, 0, 3 );
Sobel( src, dy, CV_16SC1, 0, 1, 3 );

Parameters

  • src: input image.
  • dx: output image with first-order derivative in x.
  • dy: output image with first-order derivative in y.
  • ksize: size of Sobel kernel. It must be 3.
  • borderType: pixel extrapolation method, see #BorderTypes
