Nonlinear filter Used to select the appropriate operator.
Aperture The dimension of the filter kernel.
Anchor The [x, y] coordinates of the anchor cell in the neighborhood. The top left corner would be [0, 0] and the bottom right corner would be [Columns-1, Rows-1]. For a 3 by 3 neighborhood, the coordinates of the geometric center would be [1, 1]. This specification allows the neighborhood to be skewed with respect to its geometric center.
