5.5. Tools¶

Utilities complementing the core functionalities. Includes post-processing and visualizations.

5.5.1. HDF interface¶

Handles saving and loading of sparse matrices to/from HDF files.

Currently supported formats:

tomotok.core.tools.hdf.cs_to_hdf(matrix: typing.Union[scipy.sparse.csc.csc_matrix, scipy.sparse.csr.csr_matrix], group: h5py._hl.group.Group): Saves compressed sparse matrix to hdf group.

tomotok.core.tools.hdf.dia_to_hdf(matrix: scipy.sparse.dia.dia_matrix, group: h5py._hl.group.Group): Saves dia matrix to hdf group.

tomotok.core.tools.hdf.hdf_to_cs(group: h5py._hl.group.Group) → typing.Union[scipy.sparse.csc.csc_matrix, scipy.sparse.csr.csr_matrix]: Loads compressed sparse matrix from hdf group.

tomotok.core.tools.hdf.hdf_to_dia(group: h5py._hl.group.Group) → scipy.sparse.dia.dia_matrix: Loads dia matrix from hdf group.

tomotok.core.tools.hdf.hdf_to_sparse(group: h5py._hl.group.Group) → scipy.sparse.base.spmatrix: Loads scipy.sparse matrix of formats (csc, csr, dia) from hdf file group.

tomotok.core.tools.hdf.sparse_to_hdf(matrix: typing.Union[scipy.sparse.dia.dia_matrix, scipy.sparse.csc.csc_matrix, scipy.sparse.csr.csr_matrix], group: h5py._hl.group.Group): Saves scipy.sparse matrix of formats (csc, csr, dia) into hdf file group.

Processing of tomography results. Planned to be expanded. Currently only power computation implemented.

tomotok.core.tools.postproc.compute_power(recs, grid)

Computes total radiated power from whole reconstruction area.

Parameters:

grid : RegularGrid

Returns:

numpy.ndarray

Contains values of total radiated power for all time slices

Transforms lines of sights into projections space parametrization.

tomotok.core.tools.projection.projection_space(chords, centre=(0, 0), magnetics=None, maglvl=1)

Parameters:

chords : tuple

centre : tuple of float

magnetics : dict

maglvl : float, list of float

Returns:

fig : matplotlib.figure
