\section{How does it work?}
\subsection{Algorithms}
\frame{\frametitle{Different steps} 
\begin{itemize}
\item Input image
\item Gray scale image
\item Edge detections: Sobel filter
\item Plate localization
\item Horizontal and vertical projections
\item Template matching
\item Output: string
\end{itemize}
}

\section{Technologies} 
\subsection{The technologies that I am using}
\frame{\frametitle{The technologies that I am using}
\begin{itemize}
\item Language: Python
\item{Libraries\begin{itemize}
                \item PyGTK: Graphical User Interface
                \item Scipy: Open/save images
                \item Numpy: Convert images to matrices
                \end{itemize}}

\frame{\frametitle{Issues}
Issues I have encountered:
\begin{itemize}
\item Performance
\item Usage of the Numpy library
\item Image processing
\end{itemize}
}

\subsection{The other technologies}
\frame{\frametitle{Other languages}
List of the most used languages for image processing:
\begin{itemize}
\item C: compiled language
\item C++: compiled language
\item Java: semi-compiled language
\end{itemize} 
\vspace{0.6cm}
What is different?
\begin{itemize}
\item Better performance
\item More lines of code in those languages
\item Different libraries
\item Easier to read and debug the Python code
\end{itemize} }
