) -> Result<()>

Calculates the first x- or y- image derivative using Scharr operator.

The function computes the first x- or y- spatial image derivative using the Scharr operator. The call

is equivalent to

Parameters

• src: input image.
• dst: output image of the same size and the same number of channels as src.
• ddepth: output image depth, see @ref filter_depths "combinations"
• dx: order of the derivative x.
• dy: order of the derivative y.
• scale: optional scale factor for the computed derivative values; by default, no scaling is applied (see #getDerivKernels for details).
• delta: optional delta value that is added to the results prior to storing them in dst.
• borderType: pixel extrapolation method, see #BorderTypes
