This demonstration illustrates 4 types of the smoothing opertors:

  1. Moving Average
    • Seperable and recursive implementation.
  2. Gaussian
    • Efficient implementation by repeated exponential filtering (N=3).
  3. Exponential
    • Implementation using a recursive filtering algorithm.
  4. Smoothing Splines

All filters are separable and are implemented recursively with a cost that independant of the window size. Each filter is characterized by its equivalent window size. The user can also specify an x-y anisotropy factor.
