This code uses a technique originally developed for facial recognition to describe shear stress distributions in open channel flow. In this approach, a synthetic database of images representing normalized shear stress distributions is formed from the training data set using recurrence plot analysis. A face recognition algorithm is then employed to synthesize the recurrence plots and transform the original database into short-dimension vectors containing similarity weights proportional...

Brainwave Analyzer
Discrete Fourier Transform of Brainwaves
The Brainwave Analyzer is NOT a finished program. So far it does do Discrete Fourier Transform of brainwaves (very slow), but does not yet do Fast Fourier Transform of brainwaves, nor does it yet calculate frequency. (Later more complete versions should be coming over the next few months.) Written in C# 2010 Access file and csv sample files included. Program assumes that access file is at: C:\Openvibe\OpenVibe.accdb The Brainwave Analyzer is a free open source program written by ??? Based... -

olego
OLego – short or long RNA-seq read mapping to discover exon junction
OLego is a program specifically designed for de novo spliced mapping of mRNA-seq reads. OLego adopts a seeding and extension scheme, and does not rely on a separate external mapper. It achieves high sensitivity of junction detection by using very small seeds (12-14 nt), efficiently mapped using Burrows-Wheeler transform (BWT) and FM-index. This also makes it particularly sensitive for discovering small exons. It is implemented in C++ with full support of multiple threading, to allow fast... -

wavelib
C Implementation of Wavelet Transform (DWT,SWT and MODWT)
Methods Implemented DWT/IDWT A decimated Discrete Wavelet Transform implementation using implicit signal extension and up/downsampling so it is a fast implementation. A FFT based implementation is optional but will not be usually needed. Both periodic and symmetric options are available. SWT/ISWT Stationary Wavelet Transform. It works only for signal lengths that are multiples of 2^J where J is the number of decomposition levels. For signals of other lengths see MODWT implementation. MODWT... -

jpegant
Embedded JPEG encoder
Jpegant is a compact JPEG encoder for embedded applications. It is intended to be executed on small microcontrollers or microprocessors. High speed and small memory usage is its main concern. It implements a subset of JPEG standard. Now the code contains JPEG decoder so if you decided to use nonstandard transform or entropy coding in encoder you still will be able to decode bitstream (provided that you keep the decoder in sync of course). Release 1.1 source code and Windows executables... -

A More Accurate Fourier Transform
Computes Accurate Fourier Transform via Explicit Integration not FFT
Fourier transform methods are used to analyze functions and data sets to provide frequencies, amplitudes, and phases of underlying oscillatory components. Fast Fourier transform (FFT) methods offer speed advantages over evaluation of explicit integrals (EI) that define Fourier transforms. It has been shown recently that EI methods can be more accurate than FFT methods (Courtney and Courtney, A More Accurate Fourier Transform) for scientific data analysis and that EI methods can be implemented... -

ezSIFT
An easy-to-use standalone SIFT library written in C/C++
*************************************************************************** Updated 06/28/2018 The ezSift project has moved to https://github.com/robertwgh/ezSIFT *************************************************************************** The SIFT (scale-invariant feature transform) algorithm is considered to be one of the most robust local feature detector and description methods. Most of the open-source SIFT implementations rely on some 3rd-party libraries. Some of them even rely on a few... -

FFTL
Templated Fast Fourier Transform in C++
Now moved to GitHub: https://github.com/CoreyShay/FFTL Provides some relatively easier to use than normal templated FFT classes written in C++. This is currently still a work in progress, but the FFT portion (complex and real) both output the correct results, and the code executes very quickly, around only 30% or so slower than the much more difficult to compile FFTW on SSE enabled platforms. Though optimized code only runs on SSE (x86) based platforms, it's a very simple matter to port... -

wmtsa-python
Discrete wavelet methods for time series analysis using python
Several python libraries implement discrete wavelet transforms. However, none of them, or at least none that I know, is aimed at scientific use. This library aims at filling this gap, in particular considering discrete wavelet transform as described by Percival and Walden. This module started as translation of the wmtsa Matlab toolbox (http://www.atmos.washington.edu/~wmtsa/), so most naming conventions and most of the code structure follows their choices. The code uses a mix of python... -
