Interpolation with Two-Parameter Cubic Filters

The two-parameter family of cubic filters have kernels of the form:



where B and C are two parameters; their variations give different approximation.

These interpolation methods additionally filter the output to improve quality of an image.

To get more information about how B and C values affect the result, refer to [Mitchell88].

To use the interpolation with two-parameter cubic filters, use the functions with the Cubic suffix (pass interpolation=ippCubic to GetSize functions).
