[Gimp-developer] Publication for level adjustment in app/gegl/gimplevelsconfig.c:gimp_levels_config_stretch_channel

[Simon-Martin Schröder <sms informatik uni-kiel de>]

Hi,

I'm a computer scientist from Kiel, Germany, and I currently work on a 
scientific image processing tool.

I found the automatic level adjustment in GIMP to be really useful, so I 
looked at the code, hoping to find some explanation on how it works.

The code in app/gegl/gimplevelsconfig.c seems to be rather simple, but 
lacks a reference. Who introduced this piece of code?
I could track it back to a refactor commit by Michael Natterer, 17 years 
ago (September 4th, 2002)[1], but then I'm lost.

I'm really curious where this simple yet powerful algorithm comes from 
and I'm looking forward to your reply.

Best regards,
Martin Schröder
