cvCornerHarris Method (image, harrisResponce, blockSize, apertureSize, k)
NamespacesEmgu.CVCvInvokecvCornerHarris(IntPtr, IntPtr, Int32, Int32, Double)

www.emgu.com/wiki
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 x block_size neighborhood. Then, it stores det(M) - k*trace(M)^2 to the destination image. Corners in the image can be found as local maxima of the destination image.

Parameters
image (IntPtr)
Input image
harrisResponce (IntPtr)
Image to store the Harris detector responces. Should have the same size as image
blockSize (Int32)
Neighborhood size
apertureSize (Int32)
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 (Double)
Harris detector free parameter.
