<H4>Produce Accuracy Report</H4>
The ``Produce Accuracy Report'' panel is used after reference classes
have been assigned to random samples.  Not every random sample needs to be
assigned to a class in order for this panel to work.
This panel contains three sections.<p>
The Report Type section allows you to select (via a Tab-control) 
one of the following reports:
<P>
<UL>
<LI> Sample Report Listing 
<LI> Error (Confusion) Matrix 
<LI> Accuracy Statistics 
</UL>
Within each section in the report is the ``Generate Report'' button.
This regenerates a new report based on the current signatures. The
report must be regenerated manually. The reports are not regenerated
each time a signature changes.<p>
The Options section contains the following question which must be 
answered using radio buttons. ``Yes'' is the default answer: <p>
Apply Mode Filter to Sample Values?
<P>
<UL>
<LI> If ``Yes'', a 3 by 3 mode filter around each sample in the classified image 
is used to determine the classified value of the sample. 
<LI> If ``No'', then no filtering is done. 
</UL>
The Report section is a scrolled text block containing the selected report.<p>
The panel has three action buttons along the bottom:
<P>
<UL>
<LI> Close: This button closes the panel. 
<LI> Save Report: This button  opens the ``Save Text Report'' panel which 
appends or overwrites text to a selected file on disk. 
<LI> Help: This button displays this help information.
</UL>
The formats of the Error (Confusion) Matrix and Accuracy Statistics
reports are based on the following documents:
