Efficient Method for Storing, Retrieving and Managing Preselected Multimedia Information, Utilizing Intersecting and Disjoint Counterparts

      Provided is an efficient method for storing raster images, and
in particular, a multiplicity of raster images which are similar in
content.

      Currently, documents are stored as individual entities,
typically as a file name in a repository.  The file name is the
user's handle to the file and the repository typically belongs to an
hierarchical structure for organizing and placing files or other
objects.  Currently, multimedia data such as raster images, videos,
voice data, and analog information or the like require great amounts
of storage.  For example, black and white raster images, as well as
color, utilize much resource in storing, retrieving and managing.
Video data also requires substantial resources.  A method is needed
for reducing overhead in the storing, retrieving and managing of such
information.  The method should be useable in conjunction with
existing compression/decompression and compaction/decompaction
methods.

      Raster encodings are implemented as a specific number of pixels
on a scan line and a number of scan lines for the image.  For
example, in a 300 dot per inch system, a portrait mode 8.5" by 11"
raster image may be 8.5*300 dots per scan line with 11*300 scan lines
per image.  In order to archive such a file, a utility to compact it
such as VM TERSE or DOS CRUNCH could be used to make a smaller file
which can be stored.  Some pixel array encoding formats for raster
images support what is termed run length encoding.  This encoding
provides a count for a group of dots which follow and the color or
gray scales...
