Description Todd 2010-12-31 18:49:44 UTC 
Version:           1.7.0 (using KDE 4.5.90) 
OS:                Linux

Dolphin has a very useful duplicate image search feature.  The problem with it, though, is it only allows for searching for duplicates in your digikam albums.  It would be really nice if it was split off to a kipi plugin, with the digikam interface being a front-end for the kipi plugin.  This would allow other applications, like gwenview, to allow you to search for duplicate images in any arbitrary folder (or folders) without needing their own independent implementation.  

Reproducible: Always
Comment 1 caulier.gilles 2010-12-31 18:53:44 UTC 
kipi-plugins have an old dupplicates search tool with KDE3, but we have implemented this function into digiKam core for a better integration. 

We (digiKam team) will not back to old way. And if we want to do it, it will not be possible because this feature is relevant of digiKam database, which is not available outside digiKam.

Comment 2 Todd 2010-12-31 18:59:53 UTC 
Is there any way the core comparison system can at least be split off into a separate library like the face recognition system is now?
Comment 3 Marcel Wiesweg 2011-01-01 16:05:39 UTC 
You will see that the code is deeply dependent on digikam's database layer.

The current implementation is based on an old predecessor which was closely modelled after the cited, even older publication. But this would not scale, so we adjusted the algorithm so that it operates directly on database data.
Comment 4 caulier.gilles 2017-12-14 22:53:24 UTC 
With digiKam 5.8.0, Search results virtual albums can be now shared through a DLNA/UPNP server.
