Debian Science Image analysis packages

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.

libCVD is a very portable and high performance C++ library for computer vision, image, and video processing. The emphasis is on providing simple and efficient image and video handling and high quality implementations of common low-level image processing function. The library is designed in a loosely-coupled manner, so that parts can be used easily in isolation if the whole library is not required. The video grabbing module provides a simple, uniform interface for videos from a variety of sources (live and recorded) and allows easy access to the raw pixel data. Likewise, the image loading/saving module provides simple, uniform interfaces for loading and saving images from bitmaps to 64 bit per channel RGBA images. The image processing routines can be applied easily to images and video, and accelerated versions exist for platforms supporting SSE.

This package contains tools and utilities using libcvd.

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.

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.
