Release version 0.5.0

New major release, adding the following features and fixing the following bugs:

Added

• New module called models:
  • VolumeGeometry: description of the volume.
  • ProjectionGeometry: description / manipulation of the projection geometry.
  • Support for unmatched pixel-voxel size, cone beam geometry, uneven volume shape.
  • Arbitrary geometry, including tilted detector.
• Convolution operator and deconvolution support.
• Support for rotating projection stack.
• Support for computing cross-correlation curves.
• Computation of PSF for pencil beam scanning with gaussian beam.
• Support for computing attenuation maps outside the corrected projector.

Fixed

• Pixel weights, when having small outliers.
• Volume mask generation
• Dimension bug in azimuthal integration.
• Inconsistency between astra-toolbox and scikit-image backends.

Warning

• Some interfaces and some internal properties have been refactored / renamed.
• There is still an inconsistency between the scikit-image and astra-toolbox backends, regarding the volume center definition.
