NOTE: The work on migrating our interactive tutorial tools from the "dead" Java applet platform to HTML5/Javascript has started.

Until they are ready, it looks like one has to use the "appletviewer" tool found in the JDK to view the interactive java examples. When the tool is installed, one can start the applet by typing "appletviewer URL", e.g.:

>> appletviewer http://www.imageprocessingbasics.com/spatial-resolution/
