Bayer CFA and drizzle versus combine RGB
First of all, THANK YOU so much for this new version 1.077. The pleasure of processing our images is all the more pleasant.
I am validating a procedure to obtain the best possible treatment for color images produced using a camera whose Bayer pattern is RGGB.
After having realized the "split channels" of my color images and in order to obtain the best "realize / ideal noise reduction ratio (ratNR)", I used the zero tab "Bayer CFA" where I used the following parameters and continued processing until integration:
* RGGB Pattern
* Adaptive Airy Disc Algorithm
* Force Bayer CFA
For stacking, I got the best results with "bayer drizzle 1.0" and "droplet size 2.59".
Thus, I obtained for each filter (R, G, B) three channels each having their own "ratNR".
For the combine RGB, I did some tests by considering all the channels R-c1, R-c2, R-c3, G-c1, G-c2, G-c3, B-c1, B-c2, B-c3 or by not considering only one channel per filter is the one with the best "ratNR" (eg, R-c2, G-c2, B-c1).
At this point, I wonder what is the best or the best strategies to test to take advantage as much as possible of the captures of our color images.
Is there a tutorial on this?
Tanks in advance and Have a nice day,
