This demonstration illustrates 4 types of the smoothing opertors:
- Moving Average
- Seperable and recursive implementation.
- Efficient implementation by repeated exponential filtering (N=3).
- Implementation using a recursive filtering algorithm.
- 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.
