Distributed Image Processing

      Described is a method which  will  provide  a  facility   to
execute computationally intensive image processing activity on an
'image server'.  This concept will be known as Distributed Image
Processing.

      The days of dedicated single task workstations are  over.
Since the advent of distributed systems,  more and more tasks,
processes, and data are spread across multiple nodes which make up a
Local Area Network (LAN).  Tasks are no longer restricted to a
single workstation.  Typically  LANs are  composed  of several
low-powered inexpensive client workstations with one or more powerful
servers.  Customer see this  environment  as  a  cost effective
computing solution.

      Today, the image processing arena seems contrary to this
prevalent LAN environment.  Image scanners and other imaging related
hardware  with accompanying  software  are  confined  to dedicated
workstations.  Most of these PC based systems are DOS based.  The DOS
environment provides very limited capabilities due to memory
constraints and other limitations.  These DOS based workstations are
be "tied up" for the length of time which image digitization and
other host-based image corrections or enhancements execute.  All of
these operations tend to be time consuming processes.

      As  previously  stated,  client  machines  in  a  LAN
environment are minimal,  relatively slow computer configurations
while the server machine has  lots  of  "horsepower" with large
amounts of fast DASD.  With this in mind,  this disclosure describes
a software  solution which  allows  time intensive image processing
activity to occur on an image server.

An example LAN is as follows:

      On this LAN,  the model 90 is the server.  An RS/6000 could
easily be substituted for the 90.  The IBM PC, PS/2 model 50, and
Computer X are the clients.  A image scanner...
