Also see my TiRG project (since 2011-01-31):
http://sourceforge.net/projects/tirg/
It's for detecting and localizing textareas in raster graphics.
Among its files there is a python script -- absolutely working.
Enjoy to do with it whatever you like -- it's my public domain.

So, my current very strict definition of similarity is:
---
2 pics are similar if my script gives for them value < 20%,
otherwise the pics are not similar.

Just admit that your algorithm doesn't work that well already :-)
Or give a solid formal definition of "similarity" and prove that your
algo works with that definition.

Never mind, people.
I've found such a pair of images in my .zipped project.
It's "sky1.jpg" and "lake1.

Title:
Obviously if we'd use it in practice (in a web-museum ?)
all pic's matrices should be precalculated only once and
stored in a table with fourty fields v00 ... v93 like:
---
pic_title v00v01v02... v93
-
http://www.nga.gov/search/index.shtm
http://deyoung.famsf.org/search-collections
etc
Seems they all offer search only by keywords and this kind.
What about to submit e.g. roses2.jpg (copy) and to find its
original? Assume we don't know its author neither its title

It's *much* better but I'm not *much* about to prove it.

I uploaded a new version of the subject with a
VERY MINOR correction in it. Namely, in line #55:
print '%12s %7.2f' % (db[k][1], db[k][0] / 3600.0,)
instead of
print '%12s %7.2f' % (db[k][1], db[k][0] * 0.001,)
I.e. I normalized it to base = 100.
Now the values of similarity can't be g
At least you could've tried to make the script more usable by adding
the possibility to supply command line arguments, instead of editing
the source every time you want to compare a couple of images.
