The first thing user needs to do is to 
       
       <a href="../../current/index.html">
       start the applet</a>.

       <br><br>
       
       You could also download the
       
       <a href="../../dtw_v4.1.tar.gz">
       source code</a>
       
       from our web-site and compile it yourself. At this point in the
       tutorial we will assume that you can access the applet and that you
       have started it.
       <br><br>

       Once the applet has loaded, you will see the following screen:

       <br><br>
       
       <img src="./images/opening_screen.gif" alt="Opening screen"
       title="Opening screen" width=650 height=700>
       <br><br>


       This screen has been partitioned into a Menu area, a Grid Path
       panel, a Test Signal panel, a Model panel, two Energy panels, 
       a Warped Output panel and a Description panel. All the elements 
       have been enclosed in a separate rectangular border for clarity. 
       <br><br>
       
       The menu items are used to choose a model, a test signal to
       recognize, a specific local constraint or a distance measurement.
       
       <br><br>

       The Model, Test Signal and Warped Output panels display the
       spectrogram of desired signal.<br><br>


       The Energy panels are used to display the energy plot of desired
       signal and model.<br><br>       

       The Grid Path panel shows the matching path between selected
       model and test signal.<br><br>
       

       The Process Description panel tells user what the applet is 
       working on, the matching cost and recognition result.<br><br>
