Please note that these modules are currently in what software companies
might call a "beta," or maybe even alpha phase.  The Image Processing
and Digital Signal Processing algorithms, have been thoroughly tested
through 5 levels of release by the khoros group, however, the avs 
wrappers which now call these algorithms have not be thoroughly debugged.
For an experienced C/AVS programmer, fixing one of these modules is
relatively straight forward; otherwise the maze of code is a mess.
Please forward us all bug reports in any case so that we can update
the archives with improved "bug-free" versions -)!

The entire AVS/khoros distribution requires 128 Mb including source,
libraries,includes, and binaries for multiple platforms.  This is
primarily a function of the vastness of the khoros code, rather
the avs implementation.

expfilter is referenced in libvmath.a
gradadp   is referenced in libvmath.a
threshold is referenced in libvmath.a   ( all determined by nm'ing .a's )

Thus I would reccomend downloading the appropriate khoros library
set for your platform, and erasing all but libvmath.a .

Khoros is available to non-profit, academic institutions through anonymous
ftp to pprg.eece.unm.edu, if you don't have disk space.... beware !

Good luck-
