Cv.CornerHarris Method (CvArr, CvArr, Int32, ApertureSize, Double)

CvCornerHarris Method (CvArr, CvArr, Int32, ApertureSize, Double)

OpenCvSharp Class Library

Runs the Harris edge detector on image. Similarly to cvCornerMinEigenVal and cvCornerEigenValsAndVecs, for each pixel it calculates 2x2 gradient covariation matrix M over block_size×block_size neighborhood.

Parameters

image: Type: OpenCvSharpCvArr
Input image.
harrisResponce: Type: OpenCvSharpCvArr
Image to store the Harris detector responces. Should have the same size as image.
blockSize: Type: SystemInt32
Neighborhood size.
apertureSize: Type: OpenCvSharpApertureSize
Aperture parameter for Sobel operator (see cvSobel). format. In the case of floating-point input format this parameter is the number of the fixed float filter used for differencing.
k: Type: SystemDouble
Harris detector free parameter.
