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... -

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... -

... values can be real numbers, symbols, or user defined symbolic expressions. Frequency domain results can be transformed to time domain via Inverse Laplace or Z Transform. Transformation between S-domain and Z-domain results can be done via Forward or Backward Derivatives (Euler Transform), Bilinear, or Impulse Invariant Transforms. Provide Bode, Gain-Phase, Nyquist, Pole-zero, Impulse, and Step response plots. Plot ranges can be set manually or automatically.

Correlated random noise generator
C++library to generate a random noise with isotropic correlation.
It is a C++ library that implements a Fourier Filtering Method (FFM) to generate Gaussian random noise with any correlation with the only requirement of isotropy in both one and two dimensions. Unlike previous FFM that are only suitable to generate disorders whose correlation Fourier Transform (FT) has an analytical expression, it should be enlightened that the present method works with any isotropic and finite correlation, even its analytic FT does not exist. -

WaveSorter
A powerful, versatile tool for offilne spike analysis and sorting
... properties (width, etc.) can be saved to disk in simple text files. WaveSorter is written in C++, utilizes the GNU Scientific Library for all computation, and is highly parallelized; on modern hardware it can handle files containing several 100,000s of waveforms per channel with almost no noticeable loss in GUI fluidity and <1sec lags for files with >1,000,000 waveforms per channel. It can be run in batch mode. It supports a wide array of binary file formats as well as ASCII text. -

astrovideoguide
Very simple web-interfase for astrospectrograph
Videoguide allows you to correct star position in case of bad guiding system of telescope. Here is software for videoguide, hardware part consists of PIC-ruled step motors, which tilt a glass plate, correcting by this tilt position of a star or other object. The guiding object is selected by operator in a part of video from gude's CCD-camera. Selected area can be preprocessing by wavelet-filter or median filter and/or histogram equalisation. -

ISAD
Individual Synaptic Activity Detection (ISAD)
ISAD is a peak detection software that detects individual (pre-)synaptic activity in microscopy images from neuronal cultures transfected with pHluorin. 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... -

xemload
Generate XEML documents from your CSV metadata records
XEML is a language that is used to represent and design plant growth experiments. Using a wizard like interface, XemLoad allows users to transform the environmental conditions records stored as CSV files into XEML files. The experiment can either be an existing XEML document or it can be created from scratch using XemLoad. Environmental Conditions must be paired with dedicated ontologies terms, the default one being the embedded XEO (Xeml Environmental Ontology). XEO was also... -

Foad is an open source software which receive an EKG Signal from scanner, WFDB database or heart sensors. Finding patient disease started by taking Fourier transform (FFT) from input signal and extract a single cycle. Based on some heuristic algorithm the most important feature like P , Q , R , S , T captured and feed to trained neural network. and so the final decision made by CNN library. As mentioned before this software also capable do some image processing on scanned paper to lower...
