[digiKam-users] Search folder for duplicates. Not working?

[woenx]

I have been playing with the Find duplicates tool. After having reconstructed
the fingerprints for my entire library, I can right click a picture, "Find
similar..." and the duplicated pictures show immediately.

However, right clicking on the album containing that picture, "Find
duplicates...", and then clicking the button "Find duplicates" at the bottom
(feels redundant), does not return the same results. Often just one or two
duplicates when there should be tenths of them, in this specific case.

As I see, the "Find duplicated" contextual option just pre-selects the
folder to search for duplicates in the "Similarity" tool. But even selecting
additional folders where I think the duplicates might be, they are not
detected.

Am I doing something wrong here? I just want to use the Fuzzy image search
on all pictures of a directory/album at once.

The Duplicates search works album related, either within one or more albums or
all albums. Each image is compared with each one. That can take a long time on
all albums, so there's a progress bar and an extra start button. The
similarity search compares the selected image against only all fingerprints,
since the last optimization, this search also works with MySQL now in a
fraction of a second. Before several minutes.

Yes, I understand that. I performed a full duplicate search in the past, and
it takes a while.

When you right click an album, and search it for duplicates, what digikam
seems to do is selecting that album and performing a duplicate search.
However, very few duplicates are found. I expected that doing that would be
the equivalent of comparing each picture inside that folder with all
pictures in the database, but it is not. Manually searching picture per
picture finds more duplicates.

I assume digikam is only searching for duplicated pictures within that
folder, not comparing that folder to the rest of the database.
