Abstract :
Implementation of signal filtering by cubic splines with recursive IIR/FIR scheme of Unser et al. recommends to use mirror boundary conditions. However, mirror boundary conditions are not always good for a given task. We show how to implement different popular boundary conditions for cubic splines into IIR/FIR recursive filtering.
