function edges = CV_CornerHarris(srcimg,blocksize,ksize,k,border_type)
//Finds edges in image using Harris algorithm
//
// Calling Sequence
// edges = CV_CornerHarris(srcimg,blocksize,ksize,k,border_type)
//
// Parameters
// srcimg: Input single-channel 8-bit or floating-point image.
// blockSize: Neighborhood size
// ksize: Aperture parameter for the Sobel() operator.
// k: Harris detector free parameter.
// border_type: border mode used to extrapolate pixels outside of the image.
//
// Description
// The function runs the Harris edge detector on the image. For each pixel (x, y) it calculates a 2 * 2 gradient covariance matrix M(x,y) over a blockSize * blockSize neighborhood. Then, it computes the following characteristic: dst(x,y) = det(M(x,y)) - k .tr(M(x,y))^2. Corners in the image can be found as the local maxima of this response map.
//
// border_type can be :
// <itemizedlist>
// <listitem>BORDER_REPLICATE: aaaaaa|abcdefgh|hhhhhhh</listitem>
// <listitem>BORDER_REFLECT: fedcba|abcdefgh|hgfedcb</listitem>
// <listitem>BORDER_REFLECT_101: gfedcb|abcdefgh|gfedcba</listitem>
// <listitem>BORDER_WRAP: cdefgh|abcdefgh|abcdefg</listitem>
// <listitem>BORDER_CONSTANT: iiiiii|abcdefgh|iiiiiii</listitem>
// </itemizedlist>
//
// This is curretly dummy function. It provides no functionality but is required
// for providing support for generating C code for OpenCV
//
// Examples
// img = CV_LoadImage('~/test.jpg',0)
// dst = CV_CvtColor(img,"CV_RGB2GRAY");
// edge = CV_CornerHarris(dst,5,3,1,"BORDER_REPLICATE");
