graphical user interface (GUI) has been developed in the scope of this  thesis. The GUI is displayed in Figure~\ref{fig:gui}.  The GUI displays the position estimate of the proposed framework, the  ground truth position based on OptiTrack, the texton histogram, the  Euclidean distances between OptiTrack and the system, the uncertainty  of the system, and the correlation between the uncertainty and the  Euclidean distance between the Optitrack and treXton estimates. The  GUI can be accessed using the \emph{Tool} menu in paparazzi.
