Package: vspline-dev (0.3.1-1)

header-only C++ template library for uniform b-spline processing

vspline aims to be as fast as possible, it's main focus is processing of bulk data, especially images. vspline can create b-splines of:

 -  real data types and their aggregates
 -  coming in strided n-dimensional memory
 -  spline order up to 24
 -  arbitrary dimensions of the spline
 -  with a reasonable selection of boundary conditions
 -  with implicit or explicit scheme of extrapolation

on the evaluation side it provides:

 -  evaluation of the spline at point locations
 -  evaluation of the spline's derivatives
 -  fast specializations for nearest neighbour and linear interpolation
 -  mapping of arbitrary coordinates into the defined range
 -  evaluation of n-dimensional arrays of coordinates ('remap' function)
 -  functor-based transform and apply functions
 -  set of functional constructs to facilitate evaluation

data handling is done with vigra data types. vspline optionally uses horizontal vectorization with Vc. coefficient generation and remap routines are multithreaded.
