This toolbox implements AM-FM demodulation and modulation domain filtering.



-----Installation-----

1. To install the toolbox, create a new directory in your 
   preferred MATLAB toolbox installation location.  Generally, 
   this would be:
     c:\matlab\toolbox\amfm
   in Windows, or:
     ~/matlab/toolbox/amfm
   in Linux/Unix.

2. Copy the contents of amfm.zip to the above directory.

3. Add new directories to MATLAB search path.  In MATLAB, open 
     File -> Set Path...
   Then use the 'Add Folder' button to add the directories
     c:\matlab\toolbox\amfm
     c:\matlab\toolbox\amfm\lib
     c:\matlab\toolbox\amfm\custom
   Hit the 'Save' button to save the changes.
   Alternatively you may directly edit the pathdef.m file to add 
   the directories to the search path.

4. The AM-FM toolbox makes use of the Steerable Pyramid Libary 
   toolbox, which must also be installed.  This toolbox can be 
   obtained from 
     http://www.cns.nyu.edu/~eero/steerpyr/ 
   Create a new directory 
   for the Steerable Pyramid Library, such as:
     c:\matlab\toolbox\matlabPryTools

5. Copy the contents of matlabPyrTools.zip to the new directory.

6. Add new directories to MATLAB search path.  In MATLAB, open 
     File -> Set Path...
   Then use the 'Add Folder' button to add the directories
     c:\matlab\toolbox\matlabPyrTools\MEX
     c:\matlab\toolbox\matlabPryTools
   Be sure that the directories are searched in the above order, 
   so that MATLAB will use the MEX files before it attempts 
   the less efficient m files in the main directory.
   Hit the 'Save' button to save the changes.

7. The AM-FM toolbox also makes use of the Image Processing 
   Toolbox, which should be installed if it is not already 
   present.  This toolbox can be obtained from:

-----Command Line Interface-----

Once the toolbox has been installed, the AM-FM toolbox help 
may be viewed by typing 
  help AMFM
at the MATLAB command prompt.




-----Graphical User Interface-----

Once the toolbox has been installed, the AM-FM toolbox GUI 
may be viewed by typing 
  AMFM_GUI
at the MATLAB command prompt.
