Description Axel Krebs 2012-05-26 19:29:45 UTC

I have to check pics pairwise quite often- it is important to find "similar" pics independant from very file format or even when slightly different sections occur. 

Background is  scientific demand which analyses differences. 

Reproducible: Always

Steps to Reproduce:
1. I guess, this is a new request.
2. maybe relatet to fuzzy search or face recognition techniques.
3. feature could be part of a plugin.
Actual Results:  
not possible

Expected Results:  
digiKam should offer this capability, at least "on demand", that could be by activating plugins. 
If not possible, use external libraries, e.g.

Dear Gilles:

I'll try too. As I have to conduct a huge number of pics comparison
quite regular, I am searching for a helper application to support, me in
doing this so far. Usually, I have to compare about 350 pics per two
weeks...

When proposing "Linux, Open Source, Photography Tethered Shooting with
digiKam"
<"http://scribblesandsnaps.wordpress.com/2012/03/12/tethered-shooting-with-digikam/">
at March 13th, 2012, it came into my mind, that digikam could even
extend its capabilities to fulfil regular, lets call it "systematic
jobs" or, regular work.

As I describe peviously, I have to compare pics on a regular base, that
is, I must check pairwise pictures, if there are any changes/
differences between those two pics.

The ideal case would be, to use two pathes (from different time-stamps,
e.g.) where individual pics are stored, and a subsequent analysis by
digikam would find individual differences between two pics.

Best would be to mark these differences visually, mayby in red or yellow
(or so) to show these differences.

Background is the aim to derive changes from two time-stamps without
checking these differences manually and faulty.

I hope, I could clarify my wish!?

Please, let me know or ask.

thank you.

Dear Gilles:

Just found: <http://www.imagemagick.org/Usage/compare/#compare> .

I would like very much to see digikam doing such a job, maybe on a basic
level.
