Cubic Spline Interpolation in C++

I am wor开发者_开发百科king 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?

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.
