// \brief computation of n-th order moment
//
//   The n-th order moment operation replaces a pixel with the expected value
//   of x^n of its surrounding pixels, in a certain neighbourhood. Here the
//   neighbourhood is a arbitrary rectangular mask, the height and width of which
//   are passed to the constructor.
//
//   A fast computation method is used which needs only seven + or - operations per
//   pixel (except for initialization of first row and column) because it uses
//   computed values of previous pixels.
