Remaining work on RCD, LMMSE and PPG demosaicers by jenshannoschwalm · Pull Request #20640 · darktable-org/darktable
1. To avoid border remaining CPU/GPU differences we have to increase the outermost margin to 9 as we did for the border 2. As the RCD-internal border algorithms was basically a PPG variant that code got deduplicated and we have that now all in ppg code. 3. Also some PPG CPU/GPU differences got fixed.
Keep the calculation for the outermost 3 photosites in PPG as we had before for less diffs. Reminder: the border of PPG demosaicer is also used for RCD and LMMSE.
