source module nabu.stitching.stitcher.pre_processing

Classes

  • PreProcessingStitching — loader to be used when save data during pre-processing stitching (on projections). Output is expected to be an NXtomo

source class PreProcessingStitching(configuration, progress=None)

Bases : SingleAxisStitcher

loader to be used when save data during pre-processing stitching (on projections). Output is expected to be an NXtomo

warning: axis are provided according to the acquisition space <https://tomo.gitlab-pages.esrf.fr/bliss-tomo/master/modelization.html>_

Attributes

  • serie_label : str — return serie name for logs

  • reading_orders — as scan can be take on one direction or the order (rotation goes from X to Y then from Y to X) we might need to read data from one direction or another

Methods

source method PreProcessingStitching.pre_processing_computation()

source property PreProcessingStitching.stitching_axis_in_frame_space

source property PreProcessingStitching.x_flips: list

source property PreProcessingStitching.y_flips: list

source method PreProcessingStitching.order_input_tomo_objects()

Raises

  • ValueError

source method PreProcessingStitching.check_inputs()

insure input data is coherent

Raises

  • ValueError

  • TypeError

source method PreProcessingStitching.compute_estimated_shifts()

Raises

  • NotImplementedError

  • ValueError

source staticmethod PreProcessingStitching.get_bunch_of_data(bunch_start: int, bunch_end: int, step: int, scans: tuple, scans_projections_indexes: tuple, reading_orders: tuple, flip_lr_arr: tuple, flip_ud_arr: tuple)

goal is to load contiguous projections as much as possible...

:param int bunch_start: begining of the bunch :param int bunch_end: end of the bunch :param int scans: ordered scan for which we want to get data :param scans_projections_indexes: tuple with scans and scan projection indexes to be loaded :param tuple flip_lr_arr: extra information from the user to left-right flip frames :param tuple flip_ud_arr: extra information from the user to up-down flip frames :return: list of list. For each frame we want to stitch contains the (flat fielded) frames to stich together

Raises

  • ValueError

source method PreProcessingStitching.compute_reduced_flats_and_darks()

make sure reduced dark and flats are existing otherwise compute them
