0.5.3 (2024-07-25)

  • Support for Python 3.12 and Numpy 2.0

0.5.2 (2024-05-24)

  • New command fluidimage-mean to compute mean of images with the new topology {class}fluidimage.topologies.mean.TopologyMeanImage.

  • New executors multi_exec_sync ({mod}fluidimage.executors.multi_exec_sync) and multi_exec_subproc_sync ({mod}fluidimage.executors.multi_exec_subproc_sync).

  • !108: save UVmat error codes in PIV files.

0.5.1 (2024-05-06)

  • Follow UVmat: change defaults and exact meaning for parameter params.multipass.smoothing_coef (=2).

0.5.0 (2024-05-02)

  • UVmat compatibility (launching in "local" mode).
  • Change defaults and exact meaning for parameters. params.multipass.smoothing_coef (=2) and params.multipass.threshold_tps (=1.5).
  • PIV saving: use float32 and save "smooth" displacement fields.

0.4.6 (2024-04-20)

  • Fix a memory leak related to Pythran in {mod}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 {class}fluidimage.topologies.splitters.Splitter.
  • Other bugfixes and improvements (name PIV files and {class}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)


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



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 {class}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 {class}fluidimage.topologies.base.Work).

Added

  • #74: New executor multi_exec_subproc defined in {class}fluidimage.executors.multi_exec_subproc.MultiExecutorSubproc based on {class}fluidimage.topologies.splitters.Splitter. Useful for operative systems that do not support forks (in particular Windows).

  • New method {func}fluidimage.topologies.base.TopologyBase.read_log_data.

0.3.0 (2024-03-05)


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 {mod}fluidimage.piv to import the PIV classes Work and Topology.

  • Module {mod}fluidimage.image2image to import classes Work and Topology for user-defined preprocessing.

  • Modules {mod}fluidimage.bos and {mod}fluidimage.optical_flow to import the corresponding Work and Topology classes.

  • The work classes {class}fluidimage.piv.Work, {class}fluidimage.preproc.Work and {class}fluidimage.optical_flow.Work now have parameters in params.series and a method {func}fluidimage.works.BaseWorkFromSerie.process_1_serie (see the examples on preprocessing and PIV).

  • The work classes {class}fluidimage.image2image.Work and {class}fluidimage.bos.Work now have a parameters in params.images and a method {func}fluidimage.works.BaseWorkFromImage.process_1_image.

  • The work class {class}fluidimage.image2image.Work has a new method {func}fluidimage.works.image2image.WorkImage2Image.display.

  • The work class {class}fluidimage.preproc.Work has a new method {func}fluidimage.works.preproc.WorkPreproc.display.
