19 from the <font face="Courier New, Courier, mono">demo</font> folder, this

21 The script opens six figure windows, one for each stage of the model, and

27 <h2>System Requirements </h2>
|
|
tomwalters@0
|
28 <p>AIM-MAT was developed using MATLAB 7 and above.</p>
|
|
tomwalters@0
|
29 <p>The package should work on any platform supporting MATLAB 6.5 or above, with
|
|
tomwalters@0
|
30 the Signal Processing Toolbox installed.</p>
|
|
tomwalters@0
|
31 <p>AIM-MAT has been tested while in development on the following platforms:</p>
|
|
tomwalters@0
|
32 <ul><li>Windows XP with MATLAB versions 6.5, 7.1, R2006a</li>
|
|
tomwalters@0
|
33 <li>Mac OS X (version 10.4 onwards) with MATLAB version 7.1 and R2007b</li>
|
|
tomwalters@0
|
34 <li>Ubuntu Linux with MATLAB versions 7.1, R2007b and R2008a</li></ul>

36 <h2>Tips for getting started</h2>
|
|
tomwalters@0
|
37 <ul>
|
|
tomwalters@0
|
38 <li>If AIM-MAT is started from the command-line with no parameters, a file-open dialogue box will be displayed. Select the .wav or .aiff file you wish to process using this box.</li>
|
|
tomwalters@0
|
39 <li>AIM-MAT is a MATLAB implementation of the Auditory Image Model. The buttons
|
|
tomwalters@0
|
40 along the top of the main AIM-MAT window correspond to stages of this model.
|
|
tomwalters@0
|
41 The model runs from left to right across the window. The calculation of any
|
|
tomwalters@0
|
42 section of the model is contingent upon the calculation of the stage before
|
|
tomwalters@0
|
43 it.</li>
|
|
tomwalters@0
|
44 <li>To enable any of the buttons at the top of the AIM-MAT window, simply check
|
|
tomwalters@0
|
45 the 'recalculate' checkbox below that button. This will automatically check
|
|
tomwalters@0
|
46 any other parts of the module that need recalculating.</li>
|
|
tomwalters@0
|
47
|
|
tomwalters@0
|
48 <li>If any section of the model needs calculating, the surround of the button
|
|
tomwalters@0
|
49 for that section will light up <font color="#0033FF">blue</font>. If the section
|
|
tomwalters@0
|
50 needs <em>re</em>calculating the button surround will light up <font color="#990000">red</font>.
|
|
tomwalters@0
|
51 Sections of the model which have been calculated have button surrounds in
|
|
tomwalters@0
|
52 <font color="#006600">dark green</font>. The section whose output is currently
|
|
tomwalters@0
|
53 displayed has the button surround illumninated in <font color="#33CC00">bright
|
|
tomwalters@0
|
54 green</font>.</li>
|
|
tomwalters@0
|
55 <li>To get the contents of the AIM-MAT workspace into the MATLAB command line workspace at any point, simply select 'Copy current data to workspace (data)' from the 'Edit' menu.</li>
|
|
tomwalters@0
|
56 <li>The plot window will show no activity for the first few frames of the output
|
|
tomwalters@0
|
57 of the SAI module. This is because it takes a finite time for the stabilised
|
|
tomwalters@0
|
58 image to build up. Use the 'Frame #' slider in the bottom left of the GUI
|
|
tomwalters@0
|
59 to move on a few frames and see the image to build up.</li>
|
|
tomwalters@0
|
60 <li>The autoscaling function should scale each plot to a reasonable level, however,
|
|
tomwalters@0
|
61 if the activity in the plot window looks to large or too small, you can use
|
|
tomwalters@0
|
62 the 'autoscale' button to re-run the autoscaling, or use the scaling slider
|
|
tomwalters@0
|
63 to choose a suitable scale for the plot.</li>
|
|
tomwalters@0
|
64 <li>AIM-MAT plots are just MATLAB figures; they can be manipulated using the
|
|
tomwalters@0
|
65 MATLAB 7 plot tools, or command line functions.</li>
|
|
tomwalters@0
|
66 <li>AIM-MAT stores parameters for a processed file in a subdirectory of that
|
|
tomwalters@0
|
67 file's directory, named after the file without the extension. If you wish
|
|
tomwalters@0
|
68 AIM-MAT to start afresh on working on a file, delete this subdirectory.</li>
