Openbr is a great project for facial detecting.
System: linuxmint 13 x86_64
Face recognition, motion / gender / age / detection
Here it‘s website: http://www.openbiometrics.org/
It‘s github page: https://github.com/biometrics/openbr
Awareness
Just need to try those cool stuff here:
The installation tutorial
http://openbiometrics.org/doxygen/latest/installation.html
But the tutorial above is for ubuntu13.04 due to that lib/package ""
The reason the OpenBR build instructions use Ubuntu 13.04 is because (I believe) the qt5-default aptitude package is not available on 12.04.
‘‘ jklontz mentioned here: http://www.linuxquestions.org/questions/linux-software-2/compiling-openbr-cmake-error-4175469037/
As what jklontz said, we would try to follow the tutorial for Mac OSX , learn the lesson there and then deploy openbr on linux.
Here is the link of a installation for Mac OS X. http://openbiometrics.org/doxygen/latest/osx_clang.html
Conclusion : You would need to install/possess many libs/packages before compiling openbr on your computer.
Materials:
1. cmake (version upper than 2.8.11 )
Notice: ubuntu12.04 doesn‘t provide cmake upper than that version. So you ought to compile that from source.
2. qt5 (version upper than 5.0)
Notice: ubuntu12.04 doesn‘t provide "qt-* " packages neither. So if you want to build openbr, you ought to have qt5 cmake files first.
www.qt-project.org has the things you can download.
3. opencv source files and libs
Let‘s compile and deploy them all :)
Step 1. compiling cmake
git clone https://github.com/Kitware/CMake cd CMake ./configure --prefix=/usr/local make make install ldconfig
Step 2. installing qt5
wget -c http://download.qt-project.org/official_releases/qt/5.3/5.3.2/qt-opensource-linux-x64-5.3.2.run chmod +x qt-opensource-linux-x64-5.3.2.run sudo ./qt-opensource-linux-x64-5.3.2.run # Then a wizard window would jump out, install it as you wish . # By default a /opt/Qt5.3.2/ will be the default directory
Step 3. building opencv
( notice opencv 3.0+ doesn‘t work with openbr 0.5 or previous releases .Openbr would detect error if opencv is 3.0+ when compiling openbr"
In file included from /usr/local/src/openbr/build/stasm/src/external_stasm/stasm/stasm/src/stasm_lib.cpp:7:0: /usr/local/src/openbr/build/stasm/src/external_stasm/stasm/stasm/include/misc.h:422:1: error: ‘CvScalar’ does not name a type make[5]: *** [stasm/CMakeFiles/stasm.dir/stasm/src/stasm_lib.cpp.o] Error 1 make[4]: *** [stasm/CMakeFiles/stasm.dir/all] Error 2 make[3]: *** [all] Error 2 make[2]: *** [stasm/src/external_stasm-stamp/external_stasm-build] Error 2 make[1]: *** [openbr/CMakeFiles/external_stasm.dir/all] Error 2 make: *** [all] Error 2
"
. so we need opencv 2.4.9 . Here its download link http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.9/opencv-2.4.9.zip/download)
unzip opencv-2.4.9.zip -d /usr/local/src # or the path you store source files cd /usr/local/src/opencv-2.4.9/ # Then use ‘cmake‘ to compile opencv sources mkdir release cd release cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local .. # # Notice when building, cmake would look for some 3rdparty modules from internet. If you see something "-- ICV: Downloading ippicv_linux_20141027.tgz... " , do not be panic, take your time. A cup of coffee is calling you :)sudo makesudo make install
Step 4. building openbr
( with the support of fresh new ‘cmake‘, cross-platform ‘qt5‘, marvellous ‘opencv‘ )
git clone https://github.com/biometrics/openbr.git cd openbr git checkout master # Or here git checkout 0.5 ## coz some times master changes a lot LOL git submodule init git submodule update # It will cost your minutes to download those sub-modules. Take that easy. # Then, try to build the openbr sudo cmake -DCMAKE_PREFIX_PATH=/opt/Qt5.3.2/5.3/gcc_64 -DOpenCV_DIR=/usr/local/src/opencv-2.4.9/release -DCMAKE_BUILD_TYPE=Release .. sudo make j4sudo make install
Step 5. building the openbr GUI
Just as what that refers:
"
Hack OpenBR! Open Qt Creator IDE $ qtcreator & From the Qt Creator "File" menu select "Open File or Project...". Select "openbr/CMakeLists.txt" then "Open". Browse to your pre-existing build directory "openbr/build" then select "Next". Select "Run CMake" then "Finish". You‘re all set! You can find more information on Qt Creator here http://qt-project.org/doc/qtcreator if you need.
"
Here is what I got after compiling:
Then you can find more you‘d like
Step More ...
Hack on the way!
Like these:
"
(Optional) Test OpenBR! $ cd openbr/scripts $ ./downloadDatasets.sh $ cd ../build $ make test (Optional) Package OpenBR! $ cd openbr/build $ sudo cpack -G TGZ (Optional) Build OpenBR documentation! $ sudo apt-get install doxygen $ cd openbr/build $ cmake -DBR_BUILD_DOCUMENTATION=ON .. $ make -j4 $ sudo apt-get install libgnome2-bin $ gnome-open html/index.html
"
Happy hacking!
