libdwt is a cross-platform discrete wavelet transform library. The library implements fast wavelet transform algorithm using lifting scheme. Biorthogonal spline wavelets also known as Cohen-Daubechies-Feauveau wavelets of order of 4 (with 4 vanishing moments) were used. The library is implemented in ... [More] C language, a demonstration application written in C++ and employing OpenCV library is enclosed. [Less]

MADNESS provides a high-level environment for the solution of integral and differential equations in many dimensions using adaptive, fast methods with guaranteed precision based on multi-resolution analysis and novel separated representations. There are three main components to MADNESS. At the ... [More] lowest level is a new petascale parallel programming environment that increases programmer productivity and code performance/scalability while maintaining backward compatibility with current programming tools such as MPI and Global Arrays. The numerical capabilities built upon the parallel tools provide a high-level environment for composing and solving numerical problems in many (1-6+) dimensions. Finally, built upon the numerical tools are new applications with initial focus upon chemistry, atomic and molecular physics, material science, and nuclear structure. Please look in the wiki for more information and project activity. Getting the sourceAnonymous, read-only source checkout: svn checkout http://m-a-d-n-e-s-s.googlecode.com/svn/local/trunk m-a-d-n-e-s-s-read-onlyDevelopers, please see the wiki Subversion page for instructions. Underneath the hoodIf you would like a glimpse at what's going on under the hood have a look at this call graph generated using the Google perftools. It nicely shows how work is funneled through the task-queue and how about 50% of the time is spent in the optimized matrix routines. The calculation computed the energy and gradient for di-nitrogen using the local density approximation on a two-core Thinkpad x61t.

This project is a collection of ways to implement the Haar Transform for image reduction. It takes advantage of various libraries such as libSDL. This software is free as in speech, take it, use it, replicate it, modify it, LEARN FROM IT. This project was created due to an apparent lack of OSS ... [More] programs utilizing only the Haar / 2D Discrete Wavelet Transform, and exists for educational purposes. However, I am learning this as I go along, so if you have experience with these transforms or programming in general and you see something probematic, report it! [Less]
