Thanks, now it compiles fine.

Actually it does not fail, it is just a warning. Just tested by
reverting the change You made:

Linking CXX shared library ..\bin\libdigikamlib.dll

Do you mean the animation on the progress bar? That's only eye candy by
Oxygen.
I think it is intended that the dialog does not close (though one can argue
that it should close)

Yes, that was there, but the code had the problems here and there. Then I
forgot to add it again.
I had the idea to do a quick face scan with high sensitivity to offer
candidates, but I dont know if I will implement that.
(the problem will be with recognition - manually added faces will cut out
different areas than the automatic detector. But we care about this when
recognition works someday)

I happened to test it now from a testing setup, and I see the problem.
Previously, it always worked for me - seems I never created new tags. It's
fixed in SVN, and a few other glitches as well.

I mean the little block that moves from left to right while scanning, it never
stops and thus mediates that there is still something in progress.

With libkface Rev: 1196626 and digikam  Rev: 1197834 clicking on the name in
the preview does still not do anything. Also now the tag view shows the whole
thumbnails instead of just the bit of the picture the face is on. If there are
two faces on a picture the "who is this" gui appears when hovering that
picture in the tag view (unknown people) yet since the whole picture is shown
one does not know which face the tag is assigned to.

Is it ok to assign tags to unknown faces while the scanning is still in
progress?

When scanning more than one tag, the expected total may be too large (multiple
assignments). For this case, I have now added a cheat. Otherwise, see below.

Dont know, I cannot reproduce anything of this. Just deleted test db and
thumbnails, and scanned from scratch.

Can anyone else please try this? I tried again with a new db and it does not
work. Maybe some uncommitted code?

I ran a new test scan... The process goes on for much longer time now,
but still stops before reaching to end... The last lines from dbgview

I remember to have seen such problems on Windows before. It's a kdelibs thing,
handling ioslave processes. Maybe something is wrong with letting processes
die after a certain timeout? Does the main icon views still work ater this?
Digikam just gives the kdelibs (KIO) a URL and waits for the results, we can't
do so much about this in digikam code.

AFAIK yes, digikam continues to work normally... Just the face
detection do not progress further. I can even start another face
detection session, seems to work ok...

I have yet another a bit annoying "feature": sometimes the "scanning
faces" dialog goes to background, or just the digikam main window is
brought into foreground... Anyway I do not like such foreground window
switching.

I must correct myself: there seems to be always one failed request...
I.e. if the slave has died in between and I try to switch view in
digikam, it does not work in first attempt. If I make another view
switch, it starts to work again.

So this is the problem: In the icon view, you tolerate the occasional glitches
of having to click twice or refresh. The scanning process depends more on
normal behavior.
Still, the KDE (on Windows) bug must be fixed.

Re: Status of face detection

Martin Klapetek
I haven't been following the whole discussion, but I have one important bug to report under last revision of branch+kface - if I put a name into the "Who is this?" box during a scan and confirm this, the picture gets removed from the 'Unknown' tag list and is moved to the name taglist, which is correct, but the name I put in will then also be added to the picture, that was it's left neighbor in the unknown list. 

Example: there are images 1.jpg 2.jpg 3.jpg with the 'Unknown' tag. I select 2.jpg and put a name into the box and hit the confirm button. The 2.jpg is moved out of 'Unknown' but the image 1.jpg has then assigned the same name as I put into 2.jpg. Which should not happen.

For me tagging a face always crashes... I will report a bug soon.

You mean there are always two images removed from unknown and assigned the
same tag when you click once? Or press Enter once?

No, only the one is removed (the proper one), the second stays (the 1.jpg), but has the same tag assigned as the removed one.

Re: Status of face detection

"Jens Müller"

Hi all,

First of all, I didn't read though the whole thread, maybee some issues are reported earlier.

I started playing with face detecting and want to share my results. First I struggle about missing haarcascades. No messages about this, only konsole debug out catch errors up. Kubuntus opencv packages do not include haarcascade files, would'nt it be better to host them inside libkface as a independend optimized set?
Then I scanned a album, the progress dialog only show that moving slider, you don't get a impression how long the hole process will take. After finishing this dialog stays while the slider moves endless. I think the dialog should close or present a short summary about found faces (better).
When you set names to face regions and start typing a list of tags is presented, but when you click with the mouse on a tag item which is not the top one the first in the list is selected instead of the clicked one.
When a face tag is assigned to a region, it was impossible for me to change that tag to another person. Do I miss something? I think clicking ore double clicking on the region or face tag should open the editor again.
When I click on on a face tag in the tag tree, a page shows up where albums and images are shown. But for me only one image per person is shown, although there are more images with tagged faces of that person. Should'nt there be a list of all tagged images?

After all that criticism I have to say that the interface looks pretty nice and detecting faces is working very well after fixing the casacade thingy. Good work!

Regards, Jens

I dont want to duplicate these files, they are really part of OpenCV and
packagers of digikam must then list them as required dependencies. They are
also pretty large (~1MB each, we use 7 or 8) so not easily included in any
package.
Nonetheless, I agree that an error message from digikam would be helpful.

Believe it or not, for me there is a percentage number and when it's at 100%,
it's not moving. Sven is also reporting the behavior you are describing. I
dont know why.
 The dialog stays and you have to click Close, that's at least consistent with
some other tools in digikam.

Is this in the thumbnail view or in the preview view? (though the code is very
similar)

In the preview view, isnt it?
That's also something I cannot reproduce.
For me, there is a label with the assigned name, and when I click on that
label, the editor is opened again.

Once confirmed, a face tag is just like any other tag, so in the Tag left side
bar panel, you will see all images where the name was assigned.
The "People" left side bar widget is different, here you get one thumbnail for
each face (multiple per image, if necessary), you get unconfirmed results, and
you get the face as thumbnail, not the whole picture.
That's how it works for me here.

Thanks for you tests.

Yes size matters (and this only for opencv duplicates), a messagebox will be fine.

The moving slider irritated me. If it is a real progress bar finishing at 100% it is fine, too. Perhaps there could be a text like 'Found %1 faces in %2 images.'?

In the preview view, the transparant face tag combobox shows a list of possible tags as you type. When you type some chars and the see the right tag in that list, clicking on it will not select it when it is not the first in the list.

Unfortunately for me not. Not by single click, not by double click, not on the presented transparent face tag, nor the presented face region.

This is how it works for me, too. I assumed the the people tag list on the left work that way, too.

Re: Status of face detection

Martin Klapetek

I'd just like to add, that I also have just the moving slider, not the progressbar (Qt4.7 KDE 4.5.3).

Does maybe the KDE version play a part in this? I use KDE 4.5.3 + libkdcraw
and libkexiv2 from KDE trunk.

KDE 4.5.2, Qt 4.6.3.
I am sure this will be fixed sooner or later, but at the moment I am lost with
these two or three problems which I cannot reproduce.
