Marcel,
Why Face detection progress dialog is modal ? We cannot continue to work on the rest of digiKam during face processing ?

> Marcel, > > Why Face detection progress dialog is modal ? We cannot continue to > work on the rest of digiKam during face processing ? No, no problem to continue working. Fixed in SVN. It was not modal (setModal(false) and dialog->show()), but the main widget was passed as parent of the dialog. Now it's a separate window, like fingerprint generator. > Same problem for me. I just tried to scan all faces. It lock to a mpeg > video file. No crash... Is this also one of the last files of an album, and the UI is still responsive, even though the scan does not progress? I cannot reproduce this problem, but it would be typical to occur at the end of an album. Probably, the FacePipeline does not emit finished() when it should. See FacePipeline::FacePipelinePriv::checkFinished(), around line 688. Can you find out if either packagesOnTheRoad or infosForFiltering is not 0 when locking?

Please excuse my ignorance... THis sounds too exciting not to try.
I found all the libkface stuff in branches not trunk so I got the graphics dir from trunk and followed the instructions in the GSoC readme... with the adition of copying the cmake modules in libkface and libkmap into the cmake modules dir... ANyway, digikam build fails with: digikam/libs/dimg/filters/bw/bwsepiasettings.cpp:120: error: ISO C++ forbids declaration of ‘RExpanderBoxExclusive’ with no type (digikam from trunk compiles fine) Maybe this is the wrong place, I just assume you guys are closer to the GSoC code than the rest of the devs. cheers. |

In addition to use libkmap and libkface from GoSC 2010 branch, digiKam
2.0.0 needs kdegraphics/libs from trunk. Your message come from a class shared by libkdcraw Gilles Caulier 2010/10/30 Jasper <[hidden email]>: > > Please excuse my ignorance...

Thanks as always Giles.
It was my bad, I thought building from libs would do libkexiv2 and libkdcraw as well. Builds fine Crashes on startup. Fine after digikam_dbcleanup Well its scanned alot of images now, and.. well, nothing that I can see. I think I miss the point of what is happening here. Aha: ERROR: Could not load classifier cascade. It doesnt crash, the dialogues all work nicely and whatever it is doing it does quickly. 100imgs ~50sec Except the my tags bit, which I assume was meant to be the tag tree, is empty. Right clicking does all the tag things expected (make new etc) and works... But no faces detected thus far. |

> Aha: ERROR: Could not load classifier cascade. Well that's not supposed to work ;-) The cascades are at the heart of the whole process. Nothing in /usr/share/opencv? Does your OpenCV packages really not contain the cascades? It seems we also need a runtime sanity check for detection.

>In the tags tab, so you see the people > unknown tag? No. The title: People Tags the button: Scan collection... etc. The colum heading: My Tags Then the single entry "My Tags" Marcel: ls -a /usr/share/opencv OpenCVConfig.cmake So I got opencv from svn, and built this first. I have been trying to keep the different versions of digikam separate, i.e putting this one in /opt/svn-branch.... but this failed miserably with libface and all that... so purging the ubuntu versions of libcv, kipi, digikam et.al and build and running was ok. This time face detection (with opencv from svn) doesnt show the "Could not load classifier cascade" error, But, face detection does nothing it seems. It runs, progress bar et, but no result ecept a popup anouncing digikam has updaed the face databse... there are a few things that may be of interest: Cascade directory located as : /usr/share/opencv/haarcascades Error: Directory Unknown with def3 entries considered invalid; not read. Scaling with darkness 0, saturation 3968, and multipliers 2.229557 1.000000 1.356650 1.000000 Converting to sRGB colorspace... Error: Directory Unknown with def3 entries considered invalid; not read. and billions of these which I always get... Warning: Directory Thumbnail, entry 0x0201: Data area exceeds data buffer, ignoring it. What is it meant to do? |

These messages come from Exiv2 lib. Using libkexiv2 from trunk, all these messages are rerouted with KDebug and can be disabled with kdebugdialog. Just unselect kexiv2 debug namespace.

As Gilles already pointed out, you can safely ignore all these errors. If you want debug output from libface, you need to compile it in debug mode (give -DCMAKE_BUILD_TYPE=Debug to cmake), it does not use kDebug. Then you 'll get console output about parameters, primary detection, face regions verified, and time needed for all this.

Thanks Marcel,
>Please ensure you really have the cascades: > >ls /usr/share/opencv/haarcascades/ >haarcascade_eye_tree_eyeglasses.xml haarcascade_lefteye_2splits.xml >haarcascade_mcs_righteye.xml All the harracascades are present. Heres the debug output: ... Verifying face (131,159 228x228) extended rect 91 119 308x308 Verifying cascade haarcascade_frontalface_alt.xml gives 0 Verifying cascade haarcascade_frontalface_default.xml gives 1 Verifying cascade haarcascade_frontalface_alt_tree.xml gives 0 Verifying cascade haarcascade_profileface.xml gives 0 Verifying cascade haarcascade_mcs_lefteye.xml gives 2 Verifying cascade haarcascade_mcs_righteye.xml gives 1 Verifying cascade haarcascade_mcs_nose.xml gives 1 Verifying cascade haarcascade_mcs_mouth.xml gives 1 Verification finished in 0.16. Votes: Frontal 1 Features 4. Face verified: 1 Total time : 0.22 sec ... (disabling digikam etc. in kdebugdialogue didnt change anything, even on restart... no drama tho) It looks to me like it found faces 8) Should a dialogue appear? Scanned images are being tagged with "Scanned for Faces" |

marcel,
I think a libkmap wraaper need to be wrapped for libmap to handle debug ouput with kdebug. Look this code : Exiv2 method handler asignation : http://dev.exiv2.org/projects/exiv2/repository/entry/trunk/src/error.hpp#L114 llibkexiv2 handler : http://lxr.kde.org/source/KDE/kdegraphics/libs/libkexiv2/libkexiv2/kexiv2_p.cpp#294 http://lxr.kde.org/source/KDE/kdegraphics/libs/libkexiv2/libkexiv2/kexiv2_p.cpp#51 Gilles _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

So all is fine on the OpenCV/libface side. In digikam, you should have a tag "People/Unknown", both words translated, assigned to this picture. Maybe the tree is hidden in the People sidebar, did you try a double click on "My tags"? The tags will also be accessible from the Tags sidebar, though you dont get the faces as thumbnails there. Does this tag not exist at all? Marcel _______________________________________________ Digikam-devel mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-devel |

Is this just a wrapper for errors? I.e. log errors rather than do printfs so the debugger can handle them? Alex On 1 Nov 2010 18:15, "Marcel Wiesweg" <[hidden email]> wrote:

No. No people unknown. No thumbnails. Could this be a database issue from 1.6 -> 2.0? Saw a few db table not found or sim... Cheers |

It's a wrapper for error and debug messages.
