Prerequisites:

Required Dependencies:

• GTK-3.0
• gtkmm-3.0
• OpenCV (with GTK3 dependencies)
• libboost
• Wt 4.9.1

IMPORTANT: Make sure that no other versions of GTK such as GTK 2.0 are installed. This will cause conflicts in building and linking OpenCV.

Instructions for installing the required packages (Ubuntu/Debian)

Installing GTK-3.0

1. To install GTK-3.0, run this command:

sudo apt-get install libgtk-3-dev

Installing OpenCV with GTK 3.0 Dependencies:

1. Install the required dependencies:

sudo apt-get install build-essential cmake git libgtk-3-dev
libavcodec-dev libavformat-dev libswscale-dev
libgstreamer-plugins-base1.0-dev libgstreamer1.0-dev
libjpeg-dev libpng-dev libtiff-dev libwebp-dev libopenexr-dev
libeigen3-dev libtbb-dev python3-dev python3-numpy
python3-matplotlib python3-pip python3-pyqt5 python3-pyqt5.qtopengl

2. Download the latest version of OpenCV:

git clone https://github.com/opencv/opencv.git
cd opencv
git checkout 4.5.4

3. Create a build directory inside the OpenCV directory and navigate to it:

mkdir build
cd build

4. Run 'cmake' with the 'WITH_GTK_3 flag set to ON'

cmake -DWITH_GTK=ON -DWITH_GTK3=ON ..

5. Build and install OpenCV

make
sudo make install

Installing Wt 4.9.1

1. Please make sure you first have the libboost dependencies: install them by running the following command

sudo apt update
sudo apt install libboost-all-dev

2. Download Wt 4.9.1 and extract the files: https://www.webtoolkit.eu/wt/download

3. After extracting the files, run the following commands to build Wt 4.9.1:

cd wt-4.9.1
mkdir build; cd build
cmake ..
make
make -C examples

3. Run the following commands within the wt-4.9.1 folder to install.

sudo make install
sudo ldconfig

More specific instructions based on platform can be accessed here: https://redmine.webtoolkit.eu/projects/wt/wiki/Wt_Installation

Running the Program

After installing GTK 3.0 and OpenCV, navigate to the working directory. You can compile the program by following these commands in your terminal:

make
./group17
make clean

Notes about running the program:

IMPORTANT: Please create a 'recordings' folder in the project directory before first run. The recorded footage files are saved here.

Please use the following command line arguments when running the program:

--docroot . --http-address 0.0.0.0 --http-port 8080

If you change the http-address to your inet IP address, then you will be able to access the WebApp from any other device on the network.
