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
