Detailed Description

benchmarking and testing code for various vspline capabilities

load an image, create a b-spline from it, and restore the original data, both by normal evaluation and by convolution with the reconstruction kernel. all of this is done several times each with different boundary conditions, spline degrees and in float and double arithmetic, the processing times and differences between input and restored signal are printed to cout.

obviously, this is not a useful program, it's to make sure the engine functions as intended and all combinations of float and double as values and coordinates compile and function as intended, also giving an impression of the speed of processing.

compile: clang++ -std=c++11 -march=native -o roundtrip -O3 -pthread -DUSE_VC roundtrip.cc -lvigraimpex -lVc or: clang++ -std=c++11 -march=native -o roundtrip -O3 -pthread roundtrip.cc -lvigraimpex

invoke: roundtrip <image file>

there is no image output.
