C++ FFT
C++ radix 2 & 3 multi-dimension complex FFT & graphical test program
This C++ code does radix 2 & 3 multi-dimension (any) complex FFT and its inverse. Array dimensions with sizes that are not 2^m 3^n are automatically zero-padded to the nearest larger size integer of the form 2^m 3^n. The new array has the original data centered, except when a dimension size is increased by an odd number, the zero padding on the left is one less than the zero padding on the right. This FFT code is in is own namespace and is in one source file and one include file. There is... -

libPGF
libPGF is an implementation of the Progressive Graphics File (PGF)
The Progressive Graphics File (PGF) is an efficient image file format, that is based on a fast, discrete wavelet transform with progressive coding features. PGF can be used for lossless and lossy compression. It's most suitable for natural images. PGF can be used as a very efficient and fast replacement of JPEG 2000. -

WaveletStat
Wavelet analysis of 1D and 2D statistical distributions
This is WaveletStat, a scientific software to analyse statistical distributions by Continuous Wavelet Transforms (CWTs). Taking an input random sample, it computes the corresponding CWT, filters out the noise based on a p-value criterion, and reconstructs a denoised model of the density function by matching pursuit iterations. The C++ code has two branches: the 1D branch can be used on 1D distributions only, while 1D2D can be used both on 1D and 2D distributions (though less optimal on 1D). ... -

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... -

ISAD
Individual Synaptic Activity Detection (ISAD)
...It computes synaptic signals from automatically segmented regions of interest and detects peaks that represent vesicle fusion events, thus, pre-synaptic activity. ISAD is based on MWA, which is a continuous wavelet transform based algorithm that employs multiple wavelets and is published as: Sokoll, S., Tönnies, K., and Heine, M. Detection of Spontaneous Vesicle Release at Individual Synapses Using Multiple Wavelets in a CWT-Based Algorithm. Med Image Comput Comput Assist Interv (MICCAI). 2012;15(Pt 1):165-72 ISAD is written in MATLAB and comes with a graphical user interface. -
