library for Particle Image Velocimetry (PIV)

This library contains functions for evaluating images from a fluid flow by means of Particle Image Velocimetry (PIV).

The PIV technique uses a sequence of at least two images that are recorded with a well controlled separation time in-between. Tracer particles that are resident in the fluid may be illuminated by a light source, mostly a laser, that has been re-shaped into a sheet of light. In this way, the average displacement and the deformation of the image texture is obtained. Applying this analyses on small samples of the images on a (rectangular) grid results into an instantaneous velocity field of the fluid flow. PIV may also be applied for other purposes, like deformations and vibrations of solid surfaces.

This library includes the core functions for image recording, processing, interrogation, PIV data validation, post-processing, input/output functions and memory allocation.

Package version:0.5.2-5


The Data Acquisition (DAC) feature, i.e. the triggering of light
sources (mostly Nd-YAGG lasers) with a camara and the recording of the
images has been disabled in the debian package for several reasons:

- The upstream package gpivtrig containing the triggering module has
not been debianized (yet).  

- The gpivtrig package uses the rtai package which has to be build 
in combination with a patche

libgpiv (0.5.2-4) unstable; urgency=low

  * Libgpiv3-dev conflicts with libgpiv2-dev. Closes: #486711

	* Changed __GpivPivPar: int_size_2 to int_size_i (initital) and 
	int_size_1 to int_size_f (final) in include/gpiv/gpiv-piv_par.h
	* Moved some GpivImageProcPar members to a new structure GpivGenPar
	containing general parameters, using key GEN in configuration.
	* Repaired gpiv_*_check_parameters_read; added *__set = TRUE to
	function properly without configuration
