View Full Version : robust image duplicate finder?

October 18th, 2008, 06:51 AM
Hey, I'm looking for a program that can compare all images within a folder and find the duplicates, then automatically delete them based on some rules (image size, dimensions, format, etc...). I found a good program that can do this on Windows (http://www.keronsoft.com/dupdetector.html) but installing under Wine fails. Is there something similar for Ubuntu?
I've tried the kipi plugin for 'find duplicate images' but I don't want to click through every duplicate and confirm the deletion (there are many images).

Yes, DupDetector for Windows is very good.
For Ubuntu/Linux, on the Find Duplicate Images (http://ubuntuforums.org/showthread.php?t=341736) thread you can find some suggestions based on fdupes (there's also the GUI version, FSlint, as suggested in Multiple Image Files (http://ubuntuforums.org/showpost.php?p=5295897&postcount=2): I tried it and it's much better than KleanSweeper (which requires KDE and won't let you automatically select for deletion "all files but the newest one" etc. in a group of duplicate). But they all find only identical images.
On Good duplicate file scanner (http://ubuntuforums.org/showpost.php?p=4677848&postcount=11) imgSeek was suggested for images, but even if I select the highest similarity grade I find only false duplicate images.

So, I suggest you GQview (http://gqview.sourceforge.net/), which lets you search duplicates for normal/high/low similarity, is very fast, shows thumbnails and reports almost no false duplicates even in "normal similarity" mode: very efficient (and it's in the repositories).

I've read also that VisiPics (http://www.visipics.info/index.php?title=Download) is a good tool: it's for Windows but works under Wine.
