pub fn corner_harris(
    src: &dyn ToInputArray, 
    dst: &mut dyn ToOutputArray,

Harris corner detector.

The function runs the Harris corner detector on the image. Similarly to cornerMinEigenVal and cornerEigenValsAndVecs , for each pixel it calculates a gradient covariance matrix over a neighborhood. Then, it computes the following characteristic:

Corners in the image can be found as the local maxima of this response map.

Parameters

• src: Input single-channel 8-bit or floating-point image.
• dst: Image to store the Harris detector responses. It has the type CV_32FC1 and the same size as src .
• blockSize: Neighborhood size (see the details on #cornerEigenValsAndVecs ).
• ksize: Aperture parameter for the Sobel operator.
• k: Harris detector free parameter. See the formula above.
• borderType: Pixel extrapolation method. See #BorderTypes.

C++ default parameters

• border_type: BORDER_DEFAULT
