Kirsch operator
The Kirsch operator or Kirsch compass kernel is a non-linear edge detector that finds the maximum edge strength in a few predetermined directions. It is named after the computer scientist Russell A. Kirsch.
== Mathematical description ==
The operator takes a single kernel mask and rotates it in 45 degree increments through all 8 compass directions: N, NW, W, SW, S, SE, E, and NE. The edge magnitude of the Kirsch operator is calculated as the maximum magnitude across all directions:
:
h_ = \rm _\sum_^\sum_^g_^\cdot f_

where z enumerates the compass direction kernels
:
\mathbf
+5 & +5 & +5 \\
-3 & 0 & -3 \\
-3 & -3 & -3
\end,\
\mathbf
+5 & +5 & -3 \\
+5 & 0 & -3 \\
-3 & -3 & -3
\end,\
\mathbf
+5 & -3 & -3 \\
+5 & 0 & -3 \\
+5 & -3 & -3
\end,\
\mathbf
-3 & -3 & -3 \\
+5 & 0 & -3 \\
+5 & +5 & -3
\end and so on.
The edge direction is defined by the mask that produces the maximum edge magnitude.
