Quote from: 50mm1200s on July 19, 2018, 10:57:33 AMThe "Drizzle" algorithm was originally invented by Andrew Fruchter and Richard Hook for images made by the Hubble Space Telescope. I worked on it a couple of years during studying, it's an amazing algo. Several astronomy software use it, the first on PC's was Iris if I'm not wrong, since a decade or more.
Found it! They call it "Bayer drizzle". The implementation seems to be from Dave Coffin (from dcraw). The software DeepSkyStacker uses it.
Would be nice to have it on HDRMerge. I'll see if Beep6581 have more information on this.
There's some papers on Drizzle, take a look in the Harvard Library for the source : -> http://adsabs.harvard.edu/abs/2002PASP..114..144F
