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)
