Re: Need help with digital alayzis

Do you want to write a script or just measure a sample?

To measure use the dropper tool in the GIMP,(picks color from image)
Select options and choose sample average and then the numbers of pixels you'd like it to sampel

It comes in RGB, you'll have to make a table in a spredsheet to convert to LAB or H_S_V spaces

Found someplace else:
 Taking a Color Sample in The Gimp    Sampling a color in The Gimp is easy.  You just click on the eye-dropper and then click on the section of the image you'd like to sample.  
 The exact color of the sample is then given as a RGB number expressed in both hexadecimal  and decimal.  Once you've read that number,  you can close the dialog in which it appears.  
 I find clicking on the eye-dropper icon in the toolbox inconvenient.  Instead, I prefer to use the keyboard shortcut.  For me, this is the simplest way to get to the color sampler tool.  
 Both the tool icon and its equivalent shortcut are nice mnemonics.    
 It's easy to remember the visual way to get to the color sampler tool if you just think of a bucket of paint.  Visualize the eye-dropper taking a small  sample of paint from that very same paint bucket.  
 If you want to remember the keyboard shortcut for the color sampler, visualize the bottom of the  eye-dropper.  It is round like a lower-case letter ``o''.  Pressing the lowercase ``o'' makes the eye-dropper the active tool in the toolbox.  
 Note that the eye-dropper does not work at all unless the image you are sampling is active.  An easy way to make the image active is to click on its title bar once.

 I need a bit of help with my biology BSc's research project; I need to
 digitally analyze the hue contents of a series of pictures, or create
 a scale of colors, and I want to do it with the GiMP.
 
 Basically, what I need to do is to take a small part of a picture of
 an animal (a rock hyrax, lovely little things ^_^) and analyze how
 much of its fur color is based on red, brown, yellow etc. The other
 option I have for analyzing colors is to make a scale of colors; from
 black to yellow through brown, for example.
 
 Sadly, my only use for the GiMP so far was making icons and headers
 and banner, not quite the professionals use I now need, and I have
 absolutely no idea on how to do such a thing with the GiMP.
 
 I'd appreciate any tip (though a tutorial would be great XD)
 Thank you,
 Meirav Rath.
