| corrector | To correct raw data for lens distortion. | Requires information about the centre and coefficients of distortion, which need to measured beforehand. | Radial lens distortion correction with sub-pixel accuracy for X-ray micro-tomography apply the standard dark-and-flat-field normalisation to raw sample projections. | (projection - dark)/(flat - dark) | |||

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%.
