[Bug 262074] New: no face are detected

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

           Summary: no face are detected
           Product: digikam
           Version: 2.0.0
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: Face Detection
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           2.0.0 (using KDE 4.5.3)
OS:                Linux

Using 2.0.0 beta 1 I tried to detect some faces. I click on "scan collection
for faces" after a few minutes, the progress bar is still moving but the
process is finished and I can click on close. But I can not see any picture in
the people/unknown tag.  The view on the right is completely empty. I can not
scroll (as in Gilles' report).

If I go back to album view and preview a pciture, if I click on "add a face
tag" nothing happens and I can not see any face tag.


Reproducible: Always

I forgot to say that I tried to change sensitivity and rerun face detection
without success.

Do you have installed OpenCV data files ? Under mandriva it's a separate rpm
for ex.

Here, all work fine...

I am runing ubuntu 10.10 and i installed all libcv, libcv-dev libcvaux libcv4
packages.
The files such as  haarcascade_frontalface_alt2.xml ... are not installed by
the packages libcv* packages but by the opencvdoc package in
/usr/share/doc/opencvdoc/examples/haarcascades/haarcascades/haarcascade_frontalface_alt2.xml.gz

Is this the problem ? digikam needs this ?

K so it seems that in a lot of places the default installs are different. Can we try to compile a list of places that packages install cascades and I can add them to the code so we can anticipate this. Otherwise I might add a parameter to specify the location of the cascades as so many people have them in different directories.

After searching into ubuntu packages, it seems that these files are considered
as examples and hence are not shipped with opencv but are shipped with the
applications using them. Maybe digikam should also include a copy of these
files.
Anyway there should be an error message appearing in the gui if the file can
not be found, otherwise we will get many similar bug reports.

Thanks for your help.

Under ubuntu 10.10, copying and uncompressing the haarcascades solved the
issue:

sudo cp -R /usr/share/doc/opencv-doc/examples/haarcascades/haarcascades
/usr/share/opencv/
cd /usr/share/opencv/haarcascades
sudo gunzip *.gz

No, we should not include them: It's 20 MB. That will be ten or twenty times
the size of the package, all of it duplicated.

And these files are not examples. They were created by researchers in a pretty
involved process from large datasets, then made available publicly. You dont do
that in an afternoon. It is the collection of haarcascades available freely in
this world. So e.g. file a bug against Ubuntu.

Ok Marcel,

I will file a bug against ubuntu. But there is still a problem in digiKam, if
the files are missing there should be an error message in the gui not in the
console I think.

On my system, opencv is complete with haarcascades files, located in
/usr/share/opencv/haarcascades, but digikam looks for them at /haarcascades.

I have had to create symbolic link /haarcascades ->
/usr/share/opencv/haarcascades and now it works.

How come it has detected an unexisting path for those files? is it hardcoded? I
haven't found an option to change haarcascades path in digikam properities.

(system is Slackware64 current)

face detection doesn't work in openSUSE 11.4 (factory) with KDE RC2 (K:D:F)
either. after downloading & unpacking opencv-doc from ubuntu repos, i found
that they were alredy included in the opencv package i'd installed. also
providing a symlink in / doesn't help, as it did according to #12.

i'll try to compile digikam2 from source now, let's see what happens...

I'm under kubuntu 10.10 and the face detection does not work.
  following this thread I tried
"sudo apt-get install-dev libcv libcv libcvaux libcv4
=>
E: Could not find package libcv
E: Could not find package libcvaux
E: Could not find package libcv4
"
libcv-dev was already installed

Then I try

"sudo apt-get install opencv-doc

sudo cp-R / usr / share / doc / opencv-doc / examples / haarcascades /
haarcascades / usr / share / opencv /
cd / usr / share / opencv / haarcascades
sudo gunzip *. gz "

Despite this manipulation, the face-detection "does not work

may be necessary to recompile it digikam?

What do you mean exactly by does not work ? what are the symptoms ? can you run
digikam in a console to check if there are some error messages about
haarcascades ?
