[Gimp-developer] Question about Neon Edge Detection Feature

["Rosenthal, David" <drosen citysoftinc com>]

Hi, I have been using GIMP for about 5 years and love working with it.
Thank you to all who have made this wonderful tool possible.
I use the edge detection filter a lot on cloud formations. Sometimes I get
results so fantastic, I wonder if there is any 'intelligence' coded into
the filter to create meaningful forms out of random data, or , is it really
finding something that we can't see. I enclose a couple of particularly
apocalyptic results.
I've tested many combinations , including applying equalization, levels,
invert etc but the best results are a simple NEON edge filter with settings
of 9/.3.
I am attaching the original photos and their 'neoned' results (using the
Spencer Kimball plugin - which gives simiar results to directly running the
Neon Edge Filter in GIMP 2.8). I reduced the size to make the overall email
smaller. (All photo's by the way are unretouched, including ...1846 which
seems to show a few weird things in the original photo: person  sitting on
cloud reading a book at about 3 o'clock along with something billowing out
clouds.)
Is it just me that gets these apocalyptic images ? (not just from clouds
too!)
I would be interested in any comments you may have on this Is question.
Thank you very much.
