# Specimens of Discriminatory Composite Portraiture - Gender Differentiation

hostname: specimensofgender

Uses a modified version of Affectivas [cpp-sdk-samples](https://github.com/Affectiva/cpp-sdk-samples/).

## Install

Install dependencies:
```bash
sudo apt libopencv-dev install libboost-system-dev libboost-filesystem-dev libboost-date-time-dev libboost-regex-dev libboost-thread-dev libboost-timer-dev libboost-chrono-dev libboost-serialization-dev libboost-log-dev libboost-program-options-dev
sudo apt install cmake build-essential git gzip

#rpi is ARM:
wget http://download.affectiva.com/linux/arm/affdex-cpp-sdk-3.1-40-linux-arm7.tar.gz
mkdir affdex-sdk
tar -xzvf affdex-cpp-sdk-*.tar.gz -C affdex-sdk
rm affdex-cpp-sdk-*.tar.gz
```

Build:
```bash
mkdir build && cd build
cmake -DOpenCV_DIR=/usr/ -DBOOST_ROOT=/usr/ -DAFFDEX_DIR=~/gender_detection/affdex-sdk ~/gender_detection/sdk-samples
make
```

To avoid ruining the SD-card too soon, mount /tmp as tmpfs. This folder will also be used to store camera frames for analysis. So to `/etc/fstab` add:

```
# tmpfs for /tmp, so we save the sd-card a bit
tmpfs           /tmp            tmpfs   defaults,noatime,nosuid   0       0
tmpfs           /var/log        tmpfs   defaults,noatime,mode=1777,size=64m 0      0
```


`sudo ln -s supervisord.conf /etc/supervisor/conf.d/specimens.conf`

Install fonts:
` cp fonts/*/*.ttf ~/.fonts/`

## Test

Some quirks in either Rasbian or the video demo require two variables to be set before running. Not doing so results in a segfault.

```
export LC_ALL=$LANG
export LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libopencv_core.so.2.4
~/gender_detection/build/video-demo/video-demo --input ~/gender_detection/image_test.jpg --data ~/gender_detection/affdex-sdk/data --draw=0 --numFaces=20
```
