In that paper, look in particular at formula 7 and figure 9 (in which it looks like panels a and c got accidentally switched). Processing, "Pyramid Methods in Image Processing", Adelson et.al., 1983. I can provide partial answers to your questions.Ī good introduction to the "pyramid" methods that are used by Zerene Stacker PMax and (I presume) by Helicon Focus Method C is provided by. Thanks a lot, and sorry if there are already answers to these subject in some place/thread, but i can't find specifically. In some other forums, someone claims that Photoshop procedure is something that "resembles" the formally named "Method A" of Helicon.Ī) Is there someone can confirm this info ? Or is a totally different logic? (maybe also someonce can infer/induct conclusions from his experience?)ī) Is there someone can address me about the photoshop method (in general i mean) and the differences between Zerene and Helicon ?Ĭ) Are there some docs/papers which i'm missed (i mean also for Zerene /Helicon procedure which i can read to go more depth) ? Instead, I can't find anything about Photoshop logic/procedure, or at least i'cant find anything with some "good level of trustness".
Thanks to documentation of Zerene and also Helicon, i've at least a little idea of which kind of algo's and logic they use (sure, i know details are not public due to commercial reasons) I'm here for the expertise that various member clearly shows, as also for Rik (his knowlegde is quite vaste of course). Hi, i'm a student interested in stacking procedure.Įven if newbie in the field, after a little search seems already clear that the big actors in this field are Zerene/Helicon.
