[Gimp-user] Histogram units
Hello, Using the newer version (2.10.6) I notice that the metrics related to the histogram doc are different from previous versions. For example, the mean for a specific image was ~128 and in the new version is ~0.692. I have evaluated a set of images with the older version and i need to add to said image set and need to evaluate the images with the histogram parameters.

Would you please report it or explain how to join that? The histogram is extremely important that it updates as adjustments are made, or else it is just guessing, undo, guess again, undo . . . -- mikeholder (via www.gimpusers.com/forums) ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list

[Gimp-user] Histogram not updating
In the version 2.9.5 I noticed the histogram was not updating as I was making adjustment, like brightness/contrast, levels, etc. Is there a setting somewhere I need to set? I remember very well in 2.8 the histogram auto updates as I make adjustments. -- mikeholder (via www.gimpusers.com/forums) ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list

I am almost positive that there are packages written specifically for marine biologists, certainly for ecologists etc. As for dealing with pictures, you can install the readimage package and then read in a jpeg as an image matrix. Let me know if you need specific help. For tuotrials (there are 100s) start with the "Other" section on the R-website and you will find books that you can buy from Amazon to user contributed tutorials and book even conveniently classified as <100 pages to more than 100 pages long.

IIRC, without any sort of plugins. I'd presume that octave supports histograms out of the box. -Stefan Maerz > ___ > gimp-user-listmailing list > gimp-user-list@gnome.org > http://mail.gnome.org/mailman/listinfo/gimp-user-list > ___ gimp-user-list mailing list gimp-user-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-user-list

You might want to use R (http://www.r-project.org/) for this sort of thing which will also allow you to do a whole bunch other calculations. It's a very powerful statistical / mathematical programming language with great graphics support. Note that since each pixel in general is a vector of 3 values typically between (0, 1) or (0, 255), you can plot each channel separately in R to give you the histogram or you can do other plots. ___ gimp-user-list mailing list gimp-user-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-user-list
Re: [Gimp-user] Histogram
Anja, I've used gimp for some rudimentary image analysis for the past four or five years. However, I've started migrating to Fiji (a fork of imagej). It streamlines much of my tasks, because it is the right tool for the job. To be direct, I don't have an answer for you, but I am interested to know if it can be done within gimp. In imagej with an image open go: Analyze>Histogram>List>File>Save As... this should give you a .xls file.

Hi everybody! I am fairly new to Gimp, but love it. I am a marine biologist and I would like to use this program for my research. I do need to export the histogram values as I need to do some calculations (pixel count and value). Is there any way I can do this? Thank you for your help.
