openbr on linuxmint13/ubuntu12.04/debian7 x64 facial recognition [Compile from source!!!]

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..run
sudo ./qt-opensource-linux-x64-5.3..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 make
sudo 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 j4
sudo 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!
