paquets d’analyse d’image de Debian Science

Ce métapaquet installe les paquets de Debian Science concernant l’acquisition d’images scientifiques. Ceux-ci peuvent être utilisés avec plusieurs paquets de Science (comme par exemple, science-dataacquisition, science-viewing et science-typesetting).


For a better overview of the project's availability as a Debian package, each head row has a color code according to this scheme:

If you discover a project which looks like a good candidate for Debian Science to you, or if you have prepared an unofficial Debian package, please do not hesitate to send a description of that project to the Debian Science mailing list

GUI program for Particle Image Velocimetry

Gpiv is a Graphic User Interface program using the GTK/GNOME libraries for Particle Image Velocimetry (PIV). The program gives a quick overview of the parameter settings of the processes and allows to change them easy, running the processes, individually or in a chain, visualizes and displays the results. The processes that may be invoked by Gpiv are:

Image processing: typical image manipulations that might be needed for PIV interrogation.

Image interrogation, resulting into estimators of particle image displacements.

Data validation to test on outliers, peak-locking effect and velocity gradients over the interrogation area's.

Data post-processing: data manipulation, spatial and time scaling to obtain a velocity field from the PIV data, calculation of spatial averages, vorticity and strain.

A collection of programs for images that are generated during a Particle Image Velocimetry (PIV) experiment. This is a technique to obtain the velocity field of a fluid flow quantitatively and is performed by tracking tracer particles that have been seeded to a fluid. The technique is also applied for observing deformations at surfaces of (solid) bodies. The package contains:

  • an image processing program for typical filtering and manipulation routines that may be convenient for PIV.
  • an image interrogation program resulting into estimators of particle image displacements.
  • validation programs to test on outliers, peak-locking effect and velocity gradients.
  • post-processing programs for data manipulation (flipping, rotation etc), spatial and time scaling, calculation of spatial averages and derivative quantities from the PIV data, like vorticity and strain.
  • miscellaneous programs and scripts to perform image format conversion, batch-processing, pipeline processing (image evaluation, validation and post-processing at once), calculation of time averages from a series of PIV data sets, data-visualization and data-manipulation.

All programs start with gpiv_.

This package contains all files used by gpivtools and gpivtools-mpi, like the man pages.

Gwyddion est un programme modulaire pour la visualisation et l’analyse des données de microscopie à sonde locale (SPM – Scanning Probe Microscopy). Il est principalement conçu pour l’analyse des données du champ de hauteur obtenues par des techniques telles que (entre autres) :

 – le microscope à force atomique (AFM – Atomic Force Microscopy) ;
 – le microscope à force magnétique (MFM – Magnetic Force Microscopy) ;
 – le microscope à effet tunnel (STM – Scanning Tunneling Microscopy) ;
 – le microscope optique en champ proche (SNOM ou NSOM – Near-field
   Scanning Optical Microscopy).
Il peut aussi être utilisé pour n’importe quelle analyse de champ de

hauteur et d’image.

Ce paquet fournit l'application principale et ses modules. Il contient également un générateur d'aperçu pour GNOME (et Xfce) permettant de créer des aperçus pour tous les types de fichier pris en charge par Gwyddion.

application légère de repérage d’image
Versions of package limereg

Il s’agit d’une application en ligne de commande pour le repérage (concordance) d’images. Elle trouve automatiquement l’alignement optimal de deux images proposées, augmentant ainsi leur analogie. Elle produit les paramètres de similitude (déplacement et rotation) et/ou l’image concordante (transformée/alignée).

L’algorithme est rapide et basé sur une optimisation par dérivée analytique avec une approche multi-modèle sans utilisation onéreuse de matrices creuses.

Teem is a coordinated group of libraries for representing, processing, and visualizing scientific raster data. Teem includes command-line tools that permit the library functions to be quickly applied to files and streams, without having to write any code. The most important and useful libraries in Teem are:

  • Nrrd (and the unu command-line tool on top of it) supports a range of operations for transforming N-dimensional raster data (resample, crop, slice, project, histogram, etc.), as well as the NRRD file format for storing arrays and their meta-information.
  • Gage: fast convolution-based measurements at arbitrary point locations in volume datasets (scalar, vector, tensor, etc.)
  • Mite: a multi-threaded ray-casting volume render with transfer functions based on any quantity Gage can measure
  • Ten: for estimating, processing, and visualizing diffusion tensor fields, including fiber tractography methods.

This package contains some simple command-line tools which provide fast and easy access to the functionality in the various libraries.
