• Building the SDK on Ubuntu 16.04

$ sudo apt-get install build-essential libopencv-dev libcurl4-openssl uuid-dev
$ wget https://download.affectiva.com/linux/gcc-5.4/affdex-cpp-sdk-4.0-75-ubuntu-xenial-xerus-x86_64bit.tar.gz
$ mkdir $HOME/affdex-sdk
$ tar -xzvf affdex-cpp-sdk-4.0-75-ubuntu-xenial-xerus-x86_64bit.tar.gz -C $HOME/affdex-sdk
$ export AFFDEX_DATA_DIR=$HOME/affdex-sdk/data
$ git clone https://github.com/Affectiva/cpp-sdk-samples.git $HOME/sdk-samples
$ mkdir $HOME/build
$ cd $HOME/build
$ cmake -DOpenCV_DIR=/usr/ -DBOOST_ROOT=/usr/ -DAFFDEX_DIR=$HOME/affdex-sdk $HOME/sdk-samples
$ make
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/affdex-sdk/lib

# The SDK statically links a forked version of OpenCV, so if you run into double free or corruption error
# then you will need to preload the OpenCV library installed from package manager
# Use this command to find the path of libopencv_core.so.2.4

$ ldconfig -p | grep libopencv_core.so.2.4
$ export LD_PRELOAD=/path/to/libopencv_core.so.2.4

• Building the SDK on CentOS 7

$ sudo yum install libcurl-devel.x86_64 libuuid-devel.x86_64 opencv-devel
$ wget https://download.affectiva.com/linux/centos-4.8/affdex-cpp-sdk-4.0-2941-centos-7-x86_64bit.tar.gz
$ mkdir $HOME/affdex-sdk
$ tar -xzvf affdex-cpp-sdk-4.0-2941-centos-7-x86_64bit.tar.gz -C $HOME/affdex-sdk
$ export AFFDEX_DATA_DIR=$HOME/affdex-sdk/data
$ git clone https://github.com/Affectiva/cpp-sdk-samples.git $HOME/sdk-samples
$ mkdir $HOME/build
$ cd $HOME/build
$ cmake -DOpenCV_DIR=/usr/ -DBOOST_ROOT=/usr/ -DAFFDEX_DIR=$HOME/affdex-sdk $HOME/sdk-samples

OpenCV-webcam-demo (c++)

Project for demoing the FrameDetector class. It grabs frames from the camera, analyzes them and displays the results on screen.

The following command line arguments can be used to run it:

-h [ --help ]                        Display this help message.
-d [ --data ] arg (=data)            Path to the data folder
-r [ --resolution ] arg (=640 480)   Resolution in pixels (2-values): width
                                     height
--pfps arg (=30)                     Processing framerate.
--cfps arg (=30)                     Camera capture framerate.
--bufferLen arg (=30)                process buffer size.
--cid arg (=0)                       Camera ID.
--faceMode arg (=0)                  Face detector mode (large faces vs small
                                    faces).
--numFaces arg (=1)                  Number of faces to be tracked.
--draw arg (=1)                      Draw metrics on screen.

Video-demo (c++)

Project for demoing the Windows SDK VideoDetector class and PhotoDetector class. It process video or image files, displays the emotion metrics and exports the results in a csv file.

The following command line arguments can be used to run it:

-h [ --help ]                        Display this help message.
-d [ --data ] arg (=data)            Path to the data folder
-i [ --input ] arg                   Video or photo file to process.
--pfps arg (=30)                     Processing framerate.
--draw arg (=1)                      Draw video on screen.
--faceMode arg (=1)                  Face detector mode (large faces vs small
                                     faces).
--numFaces arg (=1)                  Number of faces to be tracked.
--loop arg (=0)                      Loop over the video being processed.
