Adapt double flatfield for "Full Radios processing pipeline"
FullRadiosPipeline, we load
n out of
n_angles full radios, where
n < n_angles in general for memory reasons.
However, double flatfield (DFF) need to load all the radios.
There are several solutions:
- Leave the things as they are: an "approximate DFF" is computed by doing the mean over
nimages (instead of
n_angles). It works well on "bamboo" with
n = n_angles /2.
- Perform the DFF step on sinograms. This certainly results in a different DFF.
- Create a "pre-process" class responsible for doing the DFF from
DataUrl, computing the average frame by frame
