Bug ID: 479181
Summary: Wish list: exact-duplicate scan based on 'uniqueHash'
Classification: Applications
Product: digikam
Version: unspecified
Platform: Other
OS: Other
Status: REPORTED
Keywords: efficiency, usability
Severity: wishlist
Priority: NOR
Component: Maintenance-Similarities
Assignee: digikam-bugs-n...@kde.org
Reporter: ottoh...@gmail.com
Target Milestone: ---
SUMMARY
***
The duplicate scanner should have option to find 'exact' duplicates which could
be really fast without fingerprints.
***
The doc,
https://docs.digikam.org/en/main_window/similarity_view.html#find-duplicates,
states the following:
"... but it will take a long time too as it has to compare every image with any
other image."
The 'Images' table has a column, 'uniqueHash', which is the hash of the bits in
the file.
Files containing the same bits *should* have the same hashes.
A simple query to find duplicate values in this column would yield a list of
unqueHash's that have duplicates, which can then be used in other table(s) to
retrieve the containing directory and file names.
This query would be fast compared to the image comparison of similarities.
Selecting this option would then disable the other similarity options on the
page.
I suspect that a large number of users simply want to find exact duplicates
when loading files that have been stored in various places, maybe under various
prior methods the user had implemented for managing their files.
This could present the file exact-duplicates in a similar manner as existing
duplicate finder.
It's simply a modification to how those similar/exact-duplicates are found.
Best regards,
.. Otto
