Tool to find duplicate images?

On windows I had several tools that would search through directories and
find images and photos that had the same content, even if their
resolutions and amount of whitespace, for instance, varied. Does anyone
know any such tools for Linux? This is opposed to classic file
comparison tools which just compare the data in the file and not how it
appears on screen.

gqview has some kind of duplicate detector, haven’t played with it
recently.

Gwenview for Kde3.5 has a plugin made for checking duplicate images,
and it works very well.

Is there a way to get the gwenview plugin to check folders recursively,
or even just search two particular folders? I can only seem to get it
to search a single folder.

Not exactly what you want, … but there is dupfinder …
‘PackMan :: Informationen zum Paket dupfinder’
(http://packman.links2linux.de/package/dupfinder/74222)

I’ve never used it myself, but saw it on Packman the other day.

Thanks, but that won’t do what I want. It searches for files whose
data, the actually bytes it contains, are the same. I want something
that looks for pictures with similar patterns of lines, colors, or some
other features independent of what the actual binary data of the file
looks like. I actually already have dupfinder installed for doing
data-based comparisons.
