| fvector | kernelLUT |
The parameters for the class genericInterpolator.
| enum lti::genericInterpolator::parameters::eInterpolationKernelType |
Types for interpolation kernels.
| BilinearKernel |
Bilinear interpolation kernel. The neighborhood size is always 2x2. This implementation is slower than the optimized version in the functor lti::bilinearInterpolation, but is provided for completeness. |
| BicubicKernel |
Bicubic interpolation. The neighborhood size is always 4x4. The kernel provided here is after Sonka et.al. pp. 67
|
| GenericKernel |
Generic interpolation. The generic interpolation uses the kernelLUT given in the parameters. |

| fvector lti::genericInterpolator< T >::parameters::kernelLUT |
Generic interpolation kernel.
If the kernelType is GenericKernel then this kernel LUT will be used. To be a valid kernel, this vector must have a size n times numSamplesPerInterval, with n even. If the validity of the kernel LUT cannot be confirmed, a Bilinear Kernel will be used instead, but setParameters will return false.
Default value: empty kernel

| eInterpolationKernelType lti::genericInterpolator< T >::parameters::kernelType |
Interpolation type to be used.
Default: Bicubic

| int lti::genericInterpolator< T >::parameters::numSamplesPerInterval |
Number of samples in the interpolation table for a unit interval.
The total number of elements in the LUT will be this value multiplied by the number of unit intervals of the interpolation kernel.
Default value: 256
