Detailed Description

template<typename T>
class pcl::BicubicBSplineInterpolation< T >

Like bicubic spline interpolation, the bicubic B-spline interpolation algorithm also interpolates from the nearest sixteen data items. However, this algorithm uses B-spline interpolating functions instead of cubic splines, which yields quite (too?) smooth results.

This implementation is based on Bicubic Interpolation for Image Scaling, by Paul Bourke. It performs a convolution with a nonseparable 2-D filter, so its performance is O(n^2).
