Re: Show only rmse statistics?

Is there also an "median" statistic available from identify? Modern astronomy application do have a median value.

Like here from PixInsight:
count (%) 100.00000
count (px) 18103008
mean 6688.487
median 7316.994
stdDev 1845.198
minimum 2133.722
maximum 10527.492

Re: identify and cr2 raw takes ages

ok, q16 is default in gentoo ... q16 makes no difference, still 52 seconds to identify the file. I am quite sure its a kstars/libgphoto2 issue.

Re: identify and cr2 raw takes ages

hmm, I am on gentoo-linux and it seems there is no q16 build-flag, they only have q8,q32,q64 in their package manager.

I will try to compile manualy

Re: Show only rmse statistics?

I found it: using "%[fx:65535*mean.r]" I get my desired number.

Re: Show only rmse statistics?

With "%[fx:mean.r]" I get decimals from 0 to 1 but I need the integer values from 0 to 65535 (with 16bit images) as seen in the verbose output. I need this numbers because they are standart in astronomical software.

Re: identify and cr2 raw takes ages

Sure, here is an image that came directly from kstars. https://drive.google.com/file/d/0B-Xegfe-6xKaNGJzZ2JtZU1RTVE/view?usp=sharing And yes, sorry, when I was writing about libgphoto I actually meant libgphoto2. I will first ask the kstars people since they implemented the library and maybe there i...

Show only rmse statistics?

Hi I use this command line to show some stats that I need from my images because I only need mean/min/max/std.dev and bit depth of all channels: And I need rmse values only, not the one that goes from 0-1 or 0-255 identify -verbose ../image.cr2 | grep 'min\|max\|mean\|deviation\|Red\|Green\|Blue\|Ov...

Re: identify and cr2 raw takes ages

It takes considerably less time if you edit delegates.xml and change the --out-type from PNG to PPM and --out-depth to 8. However, you do lose image information if you make this change, but identify works much faster-- the command completed in 3 seconds rather than 16. Sorry I need exact values fro...

All the time will be in whatever delegate is used: dcraw or ufraw. "-verbose" will tell you which is used.

For a while, IM included a multi-threaded version of dcraw, but it wasn't reliable.

Re: identify and cr2 raw takes ages

Thank you very much for your anwers! I just found out there seems to be a difference in files acquired via libgphoto and those directly from the camera. My raws where read with kstars/ekos (astronomy) via USB from my camera and it uses libgphoto to do that. My thought was gphoto reads the raw as it ...
