I think a series of these would look fantastic as tiles.

Liking the phone case, but I will need to save up a stash to get it!

trandoductin: the lotus is so beautiful, the illusion effect worked really well! are the original images yours?

No they're not I know I am entering a gray area of the law.

Not sure if you folks had seen these... (All of my Amalgamations on Flickr).

They were from a few years ago. I used imagemagick convert initially to handle the blending (because I could do much larger image sets faster than trying to adjust opacity on a per-image basis in GIMP).

To verify the results against Salavons initial work years and years ago, here is my result of the Playboy centerfolds (All of the 1970's):

Which I then began extending to other things, like all of the Sports Illustrated Swimsuit Edition covers:

I then moved on to photographer Martin Schoeller's close up portraits:

My two favorites were George Walken/Christopher Clooney:

And all the "Dreamy" men in the list:

From there I basically started looking at much longer averaging sets, and settled into music videos. I would dump all of the frames of the music video and use a custom script for G'MIC to mean average all of the images (well over 5000-6000 images per video):

A little while back I had a look at the average movie covers from Netflix that were suggested to me by their algorithms:

Apparently, doing puny music videos wasn't quite enough for me. Here's where I'm currently focusing some efforts:

cool to see PatDavid.
have you seen that video a while ago where they average all episodes of "Friends" into one show...I got a major headache after watching 2 minutes of it.

patdavid · **Posted:** Wed Oct 07, 2015 2:33 pm **(#70)**

Yep, wasn't the friends video just all of the episodes played over each other (audio included)?

yeah, i think that was it... did you watch it and did it give you a headache?

seeing these makes me itch to try ImageMagick to do it to a larger sets of images now

(damn you PatDavid! shake fist at sky)

Tin, you will get very good outcomes in your ImageMagick tries

A while back I came across this page of gimp plugins for astronomy:
http://hennigbuam.de/georg/gimp.html

Merge Layers might be useful here:

Quote:

Merges all layers. You can choose, which method for the mean value you want: Arithmetic, geometric, median, sigma median (1 or 2 pass).
Sigma median is a median of all values inside [median-sigma;median+sigma] with sigma the standard deviation.
The pixel values are weighted by alpha value (for arithmetic and geometric mean value), and ignored (for all median mean values) if alpha channel is 0.
You can mulitply each pixel value by a given constant and then add a given constant (before calculating the mean value!).
A preview widget lets you decide which is the best method for you.

Haven't tried it...ymmv

Interesting script (that Merge all).
here are results for Arithmetic, geometric, median, sigma median (1 or 2 pass).
from 49 images of Jesus

I did bump up the contrast to make it pop more ..but i think i am leaning toward the sigma median ones.

These actually remind me of my personal favorite of all of my blends:

Mr. Presidents

Mr. Presidents by Pat David, on Flickr

A mean/median blend of all of the U.S. Presidential portraits. I'm actually going to print this really large soon and hang it in my house.

nice the colors remind me of old portraits like something from the harry potter movies
here's one from about 80 images of buddha.

I wrote a very simple script to aid in scaling layer in order to align images.
First rotate your working layer so that it's straight, have two guides (left guide and right guide) for the left and the right eye of the reference image ,
Then move the layer you want to scale to fit so that left eye is lined up with left guide.
You then simply supply the script with x-coord of left-guide and right-guide, and your the new-right x-coord which is the x-coordinate of the right eye of the layer you want to scale so that it'll scale the layer to the right size so that you when you move and match up left eye to left guide, right eye will line up with right guide.

average of 115 images of Buddha.
used eyes to align (I used the above script) but it still involved a lot of tedious repetitive work.
