Release notes#

0.4.6 (2024-04-20)#

Fix a memory leak related to Pythran in fluidimage.calcul.subpix (see !97).
Performance optimizations for PIV.
Remove params.piv0.coef_correl_no_displ (old useless parameter).
Add option --version to fluidimage apps.
fluidimage-monitor: show time info.
Internal: better fft and correl with more testing.

0.4.5 (2024-04-17)#

Performance optimizations for PIV (- ~40% of CPU time without TPS)

0.4.4 (2024-04-16)#

fluidimage-monitor Textual app to monitor executions of topologies.
Update and test doc/examples/piv_as_real.
Support pip install fluidimage[all].
Change in PIV file names (can now be something like “piv02ab.h5”).

0.4.3 (2024-03-27)#

!85: fluidpivviewer.
!84: multi_exec_async using fluidimage.topologies.splitters.Splitter.
Other bugfixes and improvements (name PIV files and fluidimage.postproc.vector_field.VectorFieldOnGrid).

0.4.2 (2024-03-20)#

Fix 2 bugs affecting PIV computations (nb_peaks_to_search and interpolation close to the borders of the image).

0.4.1 (2024-03-20)#

Fix a bug affecting PIV results (forget to rename a private method)!

0.4.0 (2024-03-18)#

Danger

0.4.0 should not be used because it contains a bug leading to wrong PIV results!

Warning

This version contains incompatible API changes documented below. It is particularly interesting because it introduces a new executor (called “multi_exec_subproc”) which should work fine on operative systems like Windows and macOS. Since this is now the default executor for these OSs, users should be able to use it without noticing.

Changed#

Parameters for fluidimage.preproc.Topology are now directly in params and no longer in params.preproc.
Change topology logs, progress bars using Rich.
Image to image functions take a tuple (key, image)
kind can be "eat key value" (see fluidimage.topologies.base.Work).

Added#

#74: New executor multi_exec_subproc defined in fluidimage.executors.multi_exec_subproc.MultiExecutorSubproc based on fluidimage.topologies.splitters.Splitter. Useful for operative systems that do not support forks (in particular Windows).
New method fluidimage.topologies.base.TopologyBase.read_log_data().

0.3.0 (2024-03-05)#

Warning

This version contains incompatible API changes documented here.

Removed#

The parameter strcouple is replaced by str_subset.
from fluidimage.preproc import PreprocBase has to be replaced by from fluidimage.preproc import Work.

Changed#

Better default for params.series.str_subset ("pairs" for PIV), params.series.ind_start ("first"), params.preproc.series.str_subset ("all1by1") and params.preproc.series.ind_first ("first").

Added#

Module fluidimage.piv to import the PIV classes Work and Topology.
Module fluidimage.image2image to import classes Work and Topology for user-defined preprocessing.
Modules fluidimage.bos and fluidimage.optical_flow to import the corresponding Work and Topology classes.
The work classes fluidimage.piv.Work, fluidimage.preproc.Work and fluidimage.optical_flow.Work now have parameters in params.series and a method fluidimage.works.BaseWorkFromSerie.process_1_serie() (see the examples on preprocessing and PIV).
The work classes fluidimage.image2image.Work and fluidimage.bos.Work now have a parameters in params.images and a method fluidimage.works.BaseWorkFromImage.process_1_image().
The work class fluidimage.image2image.Work has a new method fluidimage.works.image2image.WorkImage2Image.display().
The work class fluidimage.preproc.Work has a new method fluidimage.works.preproc.WorkPreproc.display().
