Function for calculaing period of a wave signals in pixels using Hilbert transform. Single or multiple profiles can be used as input for calculating distribution of periods.
HILBERT2 Extract instantaneous envelope and frequency from a bandlimited signal via Hilbert transform. [ENV FREQ] = HILBERT2(X,FS), for vectors X, returns estimates of the instantaneous envelope and frequency. X is assumed to be a...
This function computes the Hilbert transform of data after it has been padded to ameliorate end effects. The method computes the Hilbert Transform according to its definition and is not optimized in terms of speed. It should also be noted that...

This function searches the interior of a signal in an attempt to find a segment that may be used in order to make the signal quasi-periodic. This can be used to reduce the influence of end effects on analyses such as the Hilbert Transform, the...
The waveform suite is designed to allow easy data retrieval from a variety of sources and to make basic waveform research quick and easy. It is a toolset that allows the creation of more sophisticated programs without having to be concerned with...
The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are...
A tool to transform single channel C code into multichannel C code. We are using pyparsing to provide a C sensitive find/replace mechanism. The resulting code is more testable than hand edited. The initial source base is DSP code.
This zip file contains 2 functions to transform generic (nD) quadratic hyper-surfaces from homogeneous form (that is [x' 1]*E*[x;1]=0) to center form (that is (x'-c')*inv(Q)*(x-c)=1, which is used for example in the ellipsoidal toolbox).
SurfBox: A set of C++ and Matlab routines implementing the surfacelet transform in arbitrary N-dimensions (N >= 2).
The surfacelet transform is described in

Tiny-DSP library contains c sources of a fast, tiny, portable and generic FFT (Fast Fourier transform) and inverse FFT. Supported are all power of two sizes (like 2,4,8,16,32,...) for one and two dimensional floating point arrays.
C routines for numeric computation of sin and cos Fourier transform of the stretched exponential function exp(-t^b), also known as Kohlrausch-Williams-Watts function. Frequently used to describe spectra of disordered systems.
pgdiff is a utility which compares the table definitions of two databases, and returns the differences as PostgreSQL commands which will transform the structure of the first database to be identical to that of the second (c.f. diff and patch).
An SVG framework in C# and an SVG-GDI+ bridge is an article through which programmers can gain knowledge about SvgNet, which is a C# library that facilitates the process of creating SVG images. Here the author explains about various classes that...
