<DIV><FONT face=Arial size=2>Hi, </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am testing several mutual information metrics,
plotting their behavior. </FONT></DIV>
<DIV><FONT face=Arial size=2>Among the metrics are the two based on
histograms:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial
size=2>MutualInformationHistogramImageToImageMetric</FONT></DIV>
<DIV><FONT face=Arial
size=2>NormalizedMutualInformationHistogramImageToImageMetric</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Do these metrics give better results when the
images have been normalised, as it is for the Viola-Wells implementation of MI,
or is this of no importance?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thank you,</FONT></DIV>
