+\begin{sectionbox}{Connected Operators}
+Connected operators are a subset of morphological image and signal
+processing operators which are strongly shape preserving. They
+can perform both high and low level image processing tasks
+such as noise removal and object recognition respectively.
+
+% NOTE: figure (or other float) ONLY allowed because sciposter.cls
+% redefines these environments to non-floating counterparts!

+\begin{sectionbox}{Extensions to Attributes}
+By choosing the object properties or \emph{attributes} on which
+filtering is based, it is possible to obtain many different types of
+filter. More importantly, it is possible to filter in ways invariant
+to operations such as rotation, translation and scaling, providing
+filtering based on shape, rather than size.

+ using elongation criteria.}
+\end{figure}
+
+In the above examples, scalar attributes are used in connected
+filters, but using vector-attributes has been developed here, and
+allows even more control over the filtering process.
+\end{sectionbox}

+\vfill
+\begin{sectionbox}{Extensions to Connectivity}
+Connected filters use the notion of connectivity, and various
+theoretical extensions are available (see poster ``Generalized
+connected morphological opertors for robust shape extraction'').
+\end{sectionbox}\\
+\begin{sectionbox}{Pattern Spectra}
+Connected filters allow very fast computation of so-called
+patter-spectra. These are histograms of the amount of image content in
+different shape and size categories (see Figure~\ref{fig:spectra}).
+These methods could also be used for content-based image retrieval.

+\begin{sectionbox}{Algorithm Development}
+New algorithms for area and attribute openings and closings based on
+Tarjan's union-find have been developed. These are currently the
+fastest algorithms available, and form the basis of a parallel
+implementation being developed.
