Detailed Description

template<class T>
class lti::triangularKernel1D< T >

one-dimensional filter kernel

This class will create a one-dimensional triangular filter kernel.

The area under the filter will be normalized to one.

The one dimesional kernel is calculated with the following equation:

with

Example:

  // the vector to be filtered:
  lti::vector<channel::value_type> data;

  // ... initialize vector here ...

  // triangular filter kernel with 3 elements with n = -1,0,+1
  lti::triangularKernel1D<channel::value_type> aKernel(3);

  // triangular filter kernel with 4 elements with n = -2,-1,0,+1
  lti::triangularKernel1D<channel::value_type> anotherKernel(4);

  lti::convolution filter;                        // convolution operator
  lti::convolution::parameters param;             // parameters
  param.setKernel(aKernel);                       // use the triangular kernel
  filter.setParameters(param);                    // set parameters

  // filter the vector and leave the result there too

  filter.apply(data);
