WWW Link. This procedure is not described as a discrete relaxation method, but
that is the best way to understand the process. Junctions are given
all possible labels as determined by an exhaustive analysis of how
physical (three-dimensional, tri-hedral) junctions can appear in a
two-dimensional image. An iterative (relaxation) procedure eliminates
all incompatible labels (i.e. those that cannot exist because
corresponding labels do not exist on the adjacent vertex). He
described the procedure in a sequential manner (assign all labels to
one vertex, assign all labels to an adjacent vertex, check these two
for compatibility along the edge between them, and remove incompatible
labels from each, add a third vertex and check compatibilities, etc.),
but could be applied in parallel as a discrete relaxation procedure.
This work also shows the advantages of a complete analysis of
problems, since many can be reduced to simple cases with proper
analysis.

This paper explored constraint satisfaction techniques as a means to limit the
need for complete combinatorial search techniques. The basic
constraint satisfaction technique is to start from a set of variables
(objects) with a set of unary constraints (or property values) on the
possible values (labels or assignments). Higher order constraints
(relations between objects) such as binary, 3-ary, etc. are either
given or synthesized from the lower order constraints. An n-ary
constraint specifies the final solution to the problem where all n
variables are labeled. The binary constraints are given by the
problems statement, but the others are synthesized by his algorithm.
This work draws heavily on the path consistency work in
Montanari (
See also Networks of Constraints: Fundamental Properties and Applications to Picture Processing. ) and the
arc-consistency work in Waltz(
See also Understanding Line Drawings of Scenes with Shadows. ).

*System: Mapsee*.
This paper discusses Mapsee-1, -2, and -3 and thus serves as the
primary reference for information about them. The conclusion is
that schema-based representations with hierarchical (arc)
consistency is best for a structured approach to
visual knowledge.
This set of systems illustrates the power of a schema based
representation and a hierarchical constraint satisfaction algorithm.
All three use a general segmentation of the image into regions and
lines segments. Constraints are given to each feature based directly
on its appearance. Mapsee-1 was a basic implementation of constraint
satisfaction (arc-consistency) with no hierarchy in the representation
and weak representations of constraints. Mapsee-2 added schemata as a
means to improve the descriptive capabilities with hierarchical
descriptions of the objects. This leads to a hierarchical arc
consistency algorithm. Mapsee-3 provided a uniform representation for
objects and relations between them (as schemata) and a more powerful
representation of alternatives in the arc consistency algorithm.
