[Bug 262074] New: no face are detected

https://bugs.kde.org/show_bug.cgi?id=262074





--- Comment #19 from Vince <vince06fr gmail com>  2011-01-08 16:10:08 ---
ok it's work

launching Digikam in a terminal show me that Digikam for cascades files at
/haarcascades like in comment #12 so i create a symbolic link like this :

sudo ln -s /usr/share/opencv/haarcascades /haarcascades

and the face-detection scanner work fine

Thanks for your work, For me Digikam is the best photo-manager

This must be fixed in libface's CMake files.
Obviously, an empty string is detected for location of opencv, to which
"/haarcascades" is appended.

Just fyi:
I am on Fedora 14, using a self prepared digikam 2.0 rpm. I had to add the link
to /haarcascades as well.

For me, neither 2.0.0-beta1 nor 2.x svn branch ever detect any faces -
the detection completes OK, but the People/Unknown tag always remains
with zero pictures.  My opencv looks correctly installed, and I tried
making the /haarcascades symlink, but it didn't help.  When I run
digikam through strace -e file and look for file syscalls involving
the haarcascades files, I don't see any. Also, the binary links
against libkface, but not libface - surely that is not right?

$ pmap `pgrep -f /opt/digikam2/bin/digikam` | grep face
00007f2b36341000    316K    200K    200K      0K      0K r-xp

/opt/digikam2/lib64/libkface.so.1.0.0
$ ldd /opt/digikam2/lib64/libkface.so.1.0.0 | grep face

Any other ideas?

Finally, this is marked as RESOLVED UPSTREAM but I can't see anywhere
that it has been reported upstream:

  https://code.ros.org/trac/opencv/report/6
  http://sourceforge.net/apps/trac/libface/report/6

Is it a libface issue or an opencv issue?

I did some investigation under my svn working directory and found
these relevant lines:

Indeed - but I dont think libkface will link without libface. It's not an
optional dependency.

ldd /usr/lib64/libkface.so | grep libface
        libface.so.0 => /usr/lib64/libface.so.0 (0x00007f6c9e26b000)
ldd /usr/bin/digikam | grep libface
        libface.so.0 => /usr/lib64/libface.so.0 (0x00007f43d9649000)

Where are your haarcascades installed then? In

We mark as upstream if it is an issue we cannot fix by changing any digikam C++
or CMake code, here it was pretty obviously a problem of installing packages
and having files in place. I will certainly not open a bug report for a
distribution which I do not use.

So how did this happen with my build?

$ ldd /opt/digikam2/bin/digikam | grep face
    libkface.so.1 => /opt/digikam2/lib64/libkface.so.1 (0x00007f078e09f000)
$ ldd /opt/digikam2/lib64/libkface.so | grep face

Here is the extract from my digikam cmake output:

--

Does the last line mean that it is automatically using the internal

internal version?  If so, what?

Yep:

Sure - so which project is the problem with: libkface, libface, or
opencv?  I checked the bug databases for all three and I couldn't see
it reported in any of them, so I am wondering if anyone else is aware
of the problem.

> I will certainly not open a bug report for a distribution which I do

Sure - distributions are downstream not upstream, anyway.  I agree
it's pointless submitting distro bugs for this OpenCV_DIR path issue,
because it is not distro-specific (I am on openSUSE 11.3, for
instance).  That's why I am checking that a bug really has been filed
upstream.

Thanks for your continued help!

Ok, the linking is not our problem, if no system libface is found an internal
version is compiled in, not linked. Wrong track. It wouldn't compile otherwise.

There is a line of output from libface where it gives the directory it is
using:
"Cascade directory located as : " << cascadeDir
probably when you begin face detection.

Btw, I think we closed as upstream because of the "/haarcascades" symlink
problem in libface.

OK, that's what I suspected.

Yep - I see this:

  Cascade directory located as : /usr/share/opencv/haarcascades

but still I get zero photos with the People/Unknown tag, even if I
slide the top slide bar all the way to the right towards Accurate and
the bottom one all the way to the left towards Sensitive.  What can I
check next?  In case it helps, here is the STDOUT/STDERR log:

  http://adamspiers.org/computing/digikam/digikam2.log

> Btw, I think we closed as upstream because of the "/haarcascades" symlink
> problem in libface.

Well there is no issue reported here:

  http://sourceforge.net/apps/trac/libface/report

but based on the above, maybe it's already fixed.

Dont you think the approx one thousand error messages about failed database
queries look suspicious? ;-)

It seems that neither the main database nor the thumbnail database have been
properly upgraded to the new schema - the error messages say that tables like
TagProperties, ImageTagProperties or CustomIdentifiers do not exist.
The very strange point here is that the version number of the database is
increased, which is usually only done in one transaction with the actual
upgrade.

Yes, I did wonder about those, but I also assumed that users would not be
expected to carefully read STDOUT/STDERR (which normally vanishes into some
hidden log file or /dev/null anyway).

Right, I guess that explains why the UI didn't warn me about an out of date
schema, although one would have hoped that the transactional nature of the
upgrade would not have allowed this :(  I will do a manual schema upgrade and
see if it fixes the issue.  Thanks again!

One more thought - if the face detection code requires certain fields to be in
the database and doesn't find them, surely it should issue some kind of error
in the UI rather than silently failing?  Shall I submit a separate bug for
this?

There may be a loophole. It's all depending on the dbconfig.xml file. It seems
if the wrong file is used - from the 1.x version - the schema update action is
null, but the update apparently succeeds. I will add a few safety nets to avoid
such a problem.

If you are a sure digikam uses the right dbconfig.xml - it's using
/opt/digikam2/share/apps/digikam/database/dbconfig.xml for you atm - it should
be sufficient that you only reduce the DBVersion flag in the settings table
from 6 to 5, at the next restart the schema update will then be done. For the
thumbnail db, from 2 to 1.

Great, thanks!

Yep - that fixed it for me:

sqlite3 Pictures/digikam4.db 'update settings set value = 5 where keyword =
"DBVersion"'
sqlite3 Pictures/thumbnails-digikam.db 'update settings set value = 1 where
keyword = "DBThumbnailsVersion"'

Now faces are being detected but there are other problems:

(1) The photos are not being tagged with 'People/Unknown'
(2) When I do a "Recognize faces" scan, it completes immediately with no
prompting - to find the detected faces, I have to manually scroll through the
photos (mentioned in bug 262212)
(3) The "Add a Face Tag" icon and entry in the right-click context menu don't
do anything (mentioned in bug 262212)

Let me know if I should submit new bugs for (1) and (3).

1) They are grouped under People/Unknown from the People left sidebar? No more
is supposed to be done. We dont want to fully tag with a temporary tag like the
Unknown tag which will usually be removed later
2) If recognition worked, the idea is that the photos are marked with the
recognized name, grouped under the name in the People's sidebar, but still have
the Ok/- buttons to confirm or reject.
3) I know, there's a bug report somewhere.

SVN commit 1218150 by mwiesweg:

Ensure that digikam is using the correct version of the dbconfig.xml file.

From now on, if a wrong file is found, a big error message is displayed at
startup.
An attempted schema update should fail.
You will need to "make install" after this change.

So the album views accessible from the left sidebar are empty for you, and you
see recognized faces only framed in the preview view?
Hm, did you check that the ioslaves from 2.0 are properly in use, not those
from 1.x?

No, the album views are populated correctly.  It's the People > Unknown tag
which always has zero photos, whether I view it from the Albums sidebar or the
People sidebar.

Right.

> Hm, did you check that the ioslaves from 2.0 are properly in use, not those

It seems kdeinit4 munges argv[0] to things like "kdeinit4: kio_digikamtags
[kdeinit] digikamtags" but based on lsof/pmap, it looks like it's using the 1.x
ioslaves.  I wrote a shell wrapper which always does this before launching
digikam:

export DIGIKAMDIR=/opt/digikam2
export PATH=$DIGIKAMDIR/bin:$PATH
export LD_LIBRARY_PATH=$DIGIKAMDIR/lib64:$LD_LIBRARY_PATH
export KDEDIRS=$DIGIKAMDIR:/usr
kbuildsycoca4

Am I missing something?

But again it seems more defensive programming is required - if an out of date
kioslave is in use and that's an issue for digikam 2.x, shouldn't digikam
detect that and either refuse to run or show an error in the GUI?
