Summary


DarkFlatFieldCorrection
Process categoryBrief description

Computational demand

for typical tomography data

(low, medium, high)

Comment(s)Reference(s)Common alternative process(es)
corrector

To apply the standard dark-and-flat-field normalisation to sample projections.

Low
  1. (projection - dark)/(flat - dark)
  2. Needs to be explicitly included in every process list that seeks this correction (specifying dark- and flat-field data in a loader, e.g. NxtomoLoader, is insufficient).



Parameters


Brief description

Savu Configurator command
>>> disp -avv

-------------------------------------------------------------------------------------
 1) DarkFlatFieldCorrection(savu.plugins.corrections.dark_flat_field_correction)     
  A Plugin to apply a simple dark and flatfield correction to raw timeseries data    
    1)            in_datasets : []
    Create a list of the dataset(s) to process.
    2)            upper_bound : None
    Set all values above the upper bound to this value.
    3)           out_datasets : []
    Create a list of the dataset(s) to create.
    4)            lower_bound : None
    Set all values below the lower_bound to this value.
    5)                pattern : PROJECTION
    Data processing pattern is 'PROJECTION' or 'SINOGRAM'.
    6)        warn_proportion : 0.05
    Output a warning if this proportion of values, or greater, are below and/or above
    the lower/upper bounds, e.g enter 0.05 for 5%.
