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 raster data, especially images. vspline can handle
- splines over real and integer data types and their aggregates - a reasonable selection of boundary conditions - spline degree up to 45 - arbitrary dimensionality of the spline - using multithreaded code - using the CPU's vector units if possible
On the evaluation side it provides
- evaluation of the spline at point locations in the defined range - evaluation of the spline's derivatives - specialized code for degrees 0 and 1 (nearest neighbour and n-linear) - mapping of arbitrary coordinates into the defined range - evaluation of nD arrays of coordinates ('remap' function) - coordinate-fed remap function ('index_remap') - functor-based remap, aka 'transform' functions - functor-based 'apply' function - restoration of the original data from the coefficients
To produce maximum performance, vspline has a fair amount of collateral code, and some of this code may be helpful beyond vspline:
- range-based multithreading with a thread pool - functional constructs using vspline::unary_functor - forward-backward n-pole recursive filtering - separable convolution - efficient access to the b-spline basis functions - extremely precise precalculated constants
data handling is done with vigra data types, using vigra::MultiArrayView for handling strided nD arrays, and vigra::TinyVector for small aggregates. vspline optionally uses horizontal vectorization with Vc, but without Vc present, it attempts to trigger the compiler's autovectorization by producing deliberately vector-friendly inner loops. bulk data processing is automatically multithreaded.
