Figure 1.1: PlugInChain structure.
The first step initializes the PlugInChain by loading the desired plugin list and building up the
graphical user interface, if required. In the plugin initialization phase, all relevant variables
are initialized and stored in the plugin ‘Settings’ structure. After every plugin is initialized
successfully, the actual (frame-based) processing of the input signal is accomplished. Each
plugin works independent of the other plugins, it is just necessary that the algorithm of a plugin
can work with signal type produced by the prior plugin. The incoming data is managed by
the framework and stored in separate arrays, so that each plugin can run with an arbitrary
frame size. The PlugInChain can be controlled either from a Graphical User Interface (GUI)
or from the command line.
1.3 Graphical User Interface (GUI)
The Graphical User Interface was designed to make the use of the PlugInChain more comfortable.
It has two different modes – the usual User mode for using and programming plugins
and a developer mode that adds some functionality for editing the files of the PlugInChain
framework itself.
The GUI-based version of the PlugInChain is started by typing
pluginchaingui(‘pluginlist’,‘ListName.cfg’);
in the MATLAB command window (from the folder where the PlugInChain is installed). This
command automatically initializes the PlugInChain and starts the GUI with the specified pluginlist
‘ListName.cfg’. The appearing graphical user interface is shown in Fig. 1.2 and is divided
into three different control panels.
1. Plugin list
2. Plugins
3. Signal processing items (Reset, Initialize, batchprocessing)
