Please try my unoficial windows installer updated to 4.1.0 : https://drive.google.com/file/d/0B7yq-xFihT0_TTZTaXlUaExlaWs/edit?usp=sharing Note : don't forget to delete libkface database file from your home directory before to run digiKam. Mine under Windows7 is located here : C:\Users\GILLES\AppData\Roaming\.kde\share\apps\libkface\database\recognition.db Gilles Caulier
Dear Gilles, Salut! Can you, please, offer that - or any new up-to-date Windows Installer of Digikam (full install). It should be mostly stable, because I cannot need a crash of my system. I can just handle single program crashes. So, if you can offer this, please feel free to do so. I would like to try face detection (if it works now regularly). If you have any questions and topics I should pay attention to, please, tell me about. I can try to serve you with comments and data. But, please, note, I don't use all of digikam's features and tools. So, if you want something specific being tested (on a Windows system), tell me. Merci beaucoup pour ton aide, à bientôt, Gunner
New pre-version of digiKam 4.2.0 windows installer is available here. https://drive.google.com/file/d/0B7yq-xFihT0_TTZTaXlUaExlaWs/edit?usp=sharing I recently released 4.1.0 installer which is available in offcial KDE download repository, but this version crash immediately when face detection is started. Crash appear when loading haar cascade XML files. There is no reason for that... The crash is inside core of OpenCV. This is not a problem relevant of digiKam. I'm sure, i found partially why : Originally, OpenCV have been compiled using minimal options enabled, to optimize install. This is the case of 4.1.0 where OpenCV 2.4.9 is installed as shared lib. Trying to find the problem using small libkface tests program, i finally tried to recompile and install whole OpenCV with all options enabled. And all work fine... So to conclude : OpenCV is a big mess puzzle, providing around 30 optional features. Playing with this options as side effect due to internal dependencies. OpenCV is really weird here. For me this problem is an important UPSTREAM dysfunction which must be reported to OpenCV team. I don't know about Linux and OSX, but there is a big chance that similar problem will appear if OpenCV compilation options are enabled or disabled... So to all packagers, please take a care about OpenCV packages. Thanks in advance. Gilles Caulier
