Geometric Hashing: A New Way to Manage Shape Data

The handling of geometric shapes is a core problem in a variety of
applications and scientific domains, from robotics, computer vision,
and digital libraries to medical imaging, molecular biology, and video
compression. Examples include the recognition by a robot of objects in
cluttered scenes, the reconstruction of shapes from partial
information, the maintainance of parts archives in a CAD/CAM system,
the structural comparison of protein molecules, and the detection of
potential drugs fitting a given receptor shape.

The method chosen to index shape features is critical. It must be
efficient enough to enable fast retrieval of relevant stored items,
accurate enough to preserve the important geometric constraints of
objects, and stable enough to remain invariant under prespecified sets
of allowed shape transformations.  Geometric hashing, a model-based,
store-and-hypothesize class of algorithms proposed over a decade ago,
is an increasingly promising approach to index-based
store-and-retrieve schemes for geometrical database access.
Successful, time-efficient, real-world applications have been built.

The Winter 1998 theme of IEEE CS&E will present the current state of
the art as practiced in a variety of successful real-world
applications, and pointers to potential new uses. Possible topics
include: -- integration of shape representation and efficient indexing
 -- extensions of the framework -- applications of the method --
analysis -- comparative studies.
