TLinearKernel = class(TCustomKernel)

Description

TLinearKernel implements a linear interpolation filter. Also known as triangle filter, tent function, roof function, Chateau function, or Bartlett window.

Mathematics

The linear triangle filter is defined as:

$$f(x)=\{\begin{array}{ll}1-|x|,& \text{if }|x|<1\\ 0,& \text{otherwise}\end{array}$$

The effective radius is $W=1.0$.
