6. Recognition

There are two types of recognition available to the user, this is either ‘batch recognition’ or ‘single recognition’. As the name suggests single recognition only processes one input pattern, while ‘batch recognition’ processes a whole directory full. Patterns that are the same format as used in the training sets are used as inputs to the recognition function. Single recognition will now be explained.

Figure 3 shows the recognition dialog. At the top there is a ‘browse’ button that enables the user to select an input pattern. The ‘preview’ button on the bottom of the window uses the white panel to display the contents of the input pattern. If a valid file has been selected, by pressing ‘recognise’ the recognition process will start. The input files used for recognition must be the same size as those used in the training sets. After the recognition has been completed a table should appear containing the results of the process. An example is shown in figure 4.

Shown in figure 5 is the batch recognition dialog. This is simply used to select a folder containing any number of unknown pattern files. All of these must be in the same format and the same size. After a folder has been selected the number of files it contains is shown in the middle of the dialog. By pressing the ‘Recog all’ button the system will recognise all of the patterns in the selected directory. A progress bar will be shown for every pattern recognised. Another example output form the system for batch recognition is shown in figure 6.
