The result of an algorithm may depend on things such as sampling and noise characteristics of the data set. Furthermore, the most common methods for estimation of parameters are discussed in this section. <P> <BR><HR> <!--Table of Child-Links--> <A NAME="CHILD_LINKS"> </A> <UL> <LI><A NAME="tex2html1595" HREF="node12.html">Image sampling</A> <LI><A NAME="tex2html1596" HREF="node13.html">Noise distributions</A> <LI><A NAME="tex2html1597" HREF="node14.html">Estimation</A> </UL> <!--End of Table of Child-Links--> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-15</I> </ADDRESS> </BODY> </HTML>
