Function image_derivatives_scharr

Function Documentation

void image_derivatives_scharr(const cv::Mat &src, cv::Mat &dst, const size_t xorder, const size_t yorder)

This function computes image derivatives with Scharr kernel.

Note

Scharr operator approximates better rotation invariance than other stencils such as Sobel. See Weickert and Scharr, A Scheme for Coherence-Enhancing Diffusion Filtering with Optimized Rotation Invariance, Journal of Visual Communication and Image Representation 2002

Parameters

  • src: Input image

  • dst: Output image

  • xorder: Derivative order in X-direction (horizontal)

  • yorder: Derivative order in Y-direction (vertical)
