freiform Posted May 12, 2016 Share Posted May 12, 2016 Hi, I'm looking for a way to automatically assess the quality of a large number of solar images in terms of focus and seeing. Ideally I would get a list that I can then use to pick my images programmatically, i.e. get the best n frames out of each 60 s interval. I would then use PI to align those images and, for example, create a time-lapse video. - I did not find a tool in PI to assess the quality of planetary/solar images. - With Autostakkert & Co., I did not find an option to just analyze the images and return some type of list containing the quality measures AS uses. Also, is it possible to use the planetary/solar stacking programs to just analyze and align and store the aligned images w/o stacking? Any hints would be appreciated!

freiform Posted May 12, 2016 Author Share Posted May 12, 2016 I'll have a look at it. I have to see how it stores there ordered files as I actually need to retain the original order for the time-lapse video. Link to comment Share on other sites More sharing options...
freiform Posted May 12, 2016 Author Share Posted May 12, 2016 (edited) Well, looking at the values calculated by PI's BatchStatistics, maybe the standard deviation can be used. Edited May 12, 2016 by freiform std.-dev., not variance Link to comment Share on other sites More sharing options...
