CornerMinEigenVal(InputArray, OutputArray, int, int, BorderTypes)

Calculates the minimal eigenvalue of gradient matrices for corner detection.

public static void CornerMinEigenVal(InputArray src, OutputArray dst, int blockSize, int ksize = 3, BorderTypes borderType = BorderTypes.Default)

Parameters

src InputArray

Input single-channel 8-bit or floating-point image.

dst OutputArray

Image to store the minimal eigenvalues. It has the type CV_32FC1 and the same size as src .

blockSize int

Neighborhood size (see the details on #cornerEigenValsAndVecs ).

ksize int

Aperture parameter for the Sobel operator.

borderType BorderTypes

Pixel extrapolation method. See #BorderTypes. #BORDER_WRAP is not supported.
