Abstract

The spline filter is a standard linear profile filter recommended by ISO/TS 16610-22 (2006). The primary advantage of the spline filter is that no end-effects occur as a result of the filter. The ISO standard also provides the tension parameter β=0.62524 to make the transmission characteristics of the spline filter approximately equal to the Gaussian filter. However, when the tension parameter β is not equal to zero, end-effects will be introduced. To resolve this problem, we analyze 14 different combinations of boundary conditions of the spline filter, and propose a set of new boundary conditions in this paper. The new boundary conditions can provide satisfactory end portions of the output form without end-effects for the spline filter when β=0.62524.
