Features scope
From Nabu minutes on 20/02/2020:
- Simple flat-fielding
- Absorption linearization (-log)
- Projection-based ring correction (e.g. double flat-fielding)
- Paganin filtering with modifications (unsharp mask)
- Simple rotation-axis finding algorithms (global, accurate, near, manual)
- Sample shifts for correction sample motion, reducing ring artifacts (aka. correct motion)
- Handling half-acquisition
- Data conversion (8/16 TIFF)
State on 03/08/2020
Done
- Simple flat-fielding
- Absorption linearization (-log)
- Projection-based ring correction (e.g. double flat-fielding)
- Paganin filtering with modifications (unsharp mask)
- Handling half-acquisition
- Simple rotation axis finding
- "Sample shifts" (horizontal/vertical)
Note: "sample shifts" is implemented, but we need a real test dataset.
Left for later
- Rotation axis estimation: need more robust methods, and a method working with half-tomo
- Half-tomo when CoR is on the left
Notes
Support for tiff and jpeg2000 is incomplete:
- When data is cast from
float32
touint16
, normalization is done slice-wise instead of volume-wise. See #146 (closed). - Advanced parameters are needed (see #147 (closed), #148 (closed)).
- The nabu configuration is not exported
Post-release
After this milestone: what to do ? When ?
In my opinion the things to do straight after the release are the following:
- Fix subvolumes stitching when
binning_z
is activated (#160 (closed)) - Fix
binning_z
on small subvolumes (#167 (closed), #168 (closed)) - Halftomo: support CoR on the left (#145 (closed))
- Auto-CoR in half tomo (important feature!)
- Account for "z series" (see minutes 05/08/2020)
- I/O: better support for tiff and jpeg2000
