Polynomial Interpolation

The Getfem++ project focuses on the development of a generic and efficient C++ library for finite element methods elementary computations. The goal is to provide a library allowing the computation of any elementary matrix (even for mixed finite element methods) on the largest class of methods and...

SurGe is a computer program which enables to generate surface as an interpolation (approximation) function of two independent variables. The program has the following basic features: > Implements an interpolation / approximation method called ABOS. > Basic input is a simple ASCII file...

Unrawel project is the library and simple command-line front-end that were written to experiment with different techniques for digital camera acquired images interpolation and processing. Areas which are covered include RAW images interpolation, images de-noising and enhancing, white balance...
