WaveLab is a collection of Matlab functions that have been used by the authors and collaborators to implement a variety of algorithms related to wavelet analysis. A partial list of the techniques made available: * orthogonal and biorthogonal wavelet transforms, * translation-invariant wavelets, * interpolating wavelet transforms, * cosine packets, * wavelet packets, * matching pursuit, and a lot more; Here is a more detailed introduction.
The goal of the CGAL Open Source Project is to provide easy access to efficient and reliable geometric algorithms in the form of a C++ library. CGAL is used in various areas needing geometric computation, such as: computer graphics, scientific visualization, computer aided design and modeling, geographic information systems, molecular biology, medical imaging, robotics and motion planning, mesh generation, numerical methods...
