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.
