Test if a point is simple or not. A point of an object is simple if in its c8 neiborhood, there is exactly one connected component of the object, and only one connected component of the background Examples : ( $|$ == object, -\/ = background)


\begin{DoxyItemize}
\item -\/ $|$ $|$ P $|$ Here p is simple in the c4 and c8 case. $|$ $|$ $|$
\end{DoxyItemize}


\begin{DoxyItemize}
\item $|$ -\/ $|$ P $|$ Here p is never simple. $|$ $|$ $|$
