Cubic Spline Interpolation in C++

Question

I am working in image processing in C++ using OpenCV. I've a problem that requires cubic interpolation of a set of data. Are there any library files that I can use for this in OpenCV?

Answer 1

I'm not sure that there are any classes in OpenCV that will do cubic interpolation.

Have you considered GSL (Gnu Scientific Library)? It should be able to help you here.

Take a look at gsl_spline.h and gsl_bspline.h.
