FluidImage
FluidImage is a free and open-source Python framework to process images of fluids (in particular with PIV), and analyse the resulting fields.
Documentation: http://fluidimage.readthedocs.org
Image processing for fluid mechanics is still dominated by proprietary tools. Such tools are not ideal when you want to understand and tweak the algorithms and/or to use clusters. There are also good and useful PIV software (PIVlab, UVmat) written in Matlab, which is itself proprietary.
With the improvement of the Python numerical ecosystem and of tools for collaborative development, one can think it is possible to build together a good community-driven library/toolkit specialized in image processing for fluid mechanics. This is our project with FluidImage.
Fluidimage has now grown into a clean software reimplementing in modern Python algorithms and ideas taken from UVmat, OpenPIV, PIVlab and PIVmat with a focus on performance, usability and maintanability. However, Fluidimage is not restricted to Particle Image Velocimetry computations (PIV, i.e. displacements of pattern obtained by correlations of cropped images) and can be used to
-
display and pre-process images,
-
compute displacement or velocity fields with PIV, Background-Oriented Schlieren (BOS) and optical flow,
-
analyze and display vector and scalar fields.
We want to make FluidImage easy (useful documentation, easy installation, nice API, usable with simple scripts and few simple graphical user interfaces), reliable (with good unittests) and very efficient, in particular when the number of images is large. Thus we want FluidImage to be able to run efficiently and easily on a personal computer and on big clusters. The efficiency is achieved by using
-
a framework for asynchronous computations (currently, we use Trio) and an associated API to define "topologies" of parallel computations.
-
parallelism to efficiently use the available cores of the Central Processing Units (CPU),
-
good profiling and efficient and specialized algorithms,
-
cutting-edge tools for fast computations with Python (in particular Pythran through Transonic).
