TCosineKernel = class(TCustomKernel)

Description

TCosineKernel implements a smooth cosine-shaped interpolation curve.

Mathematics

The cosine filter function is defined as:

$$f(x)=\{\begin{array}{ll}\frac{\cos (\pi x)+1}{2},& \text{if }|x|<1\\ 0,& \text{otherwise}\end{array}$$

The effective radius is $W=1.0$.
