\begin{frame} \frametitle{Introduction - Motivation} \begin{itemize} \item Automatic Classification system for tobacco leaves with features based on multispectral images. \item Faster, reduced subjectivity, 'fairer' efficient system output than manual inspection. \end{itemize} \end{frame}
%------------------------------------------------
\begin{frame} \frametitle{Introduction - Previous Work} \begin{itemize} \item Msc thesis of Imad Benkhaled, 2014. \item Geometric Separability Index (GSI) for class separability measure, SVM for classification. \item Multispectral features are better than conventional color features (RGB, Lab*).
\end{itemize} \end{frame}
%------------------------------------------------ \begin{frame} \frametitle{Methods - Proposed Work} \begin{columns}[c]
\column{.75\textwidth} \begin{itemize} \item 'Weak' separability of individual features (recognition slightly better than random guess) can be combined build a strong classifier.\cite{zhu2009multi} \end{itemize} \column{.15\textwidth} \pause \textbf{Boosting} \end{columns}

Learn a separate metric (or representation) on the current data, which satisfies this criteria.\cite{weinberger2005distance} \end{itemize} \column{.15\textwidth} \pause \textbf{Metric Learning} \end{columns}

\begin{frame} \frametitle{Experiments - Current Challenges} \begin{itemize} \item Important to see if classifier parameters and number of word choices affect each other. \pause \item Time consuming to verify. To check correlation and/or optimality of number words, we did experiments with 50 samples per class, only the 4 CF classes. \end{itemize} \end{frame} %------------------------------------------------
\begin{frame} \frametitle{Results} \begin{itemize} \item Optimality of number of words is checked using Support Vector Machine with Chi square kernel.
\pause \begin{figure} \fontsize{10}{12}\selectfont \includegraphics[width=0.9\linewidth]{untitled.eps} \end{figure} \pause \item For reasonably high regularization parameter value, the result and the parameter value are uncorrelated. \end{itemize} \end{frame}
