Davis, L.S.,
Hierarchical Relaxation for Shape Analysis,
PRIP78(275-279).
Discrete relaxation applied to a multilevel grammar specification of
shapes. Apply the relaxation at all levels and eliminate
assignments at upper or lower levels when a subpart or superpart is
removed.

Discrete relaxation (which is important for parallel
representations (implementations)) applied to a graph matching
problem. Desire to have a complete graph, but this is not
practical due to increased cost (especially for hardware
implementation), therefore use sparse graph - proximity and very
large regions are used. Give initial interpretations, filter on
unary constraints (intrinsic properties). Generate all pairs on the
graph arcs and filter these (use these to filter the node
labels).

Similar to Harlow, Baker, Underwood, Dudani(

et al. Using features
tends to reduce possibilities of matching elements (unique features
occur), and generally they can be consistently located. This
matching is done at the 2-D level, 3-D is derived later, but the
features can be used in the 3-D descriptions process. Lines,
vertices, and regions are encoded in a graph structure which is
used in the matching. Use highly descriptive unique points to seed
the match and have a set of parallel processes at each seed grow
out and compete or merge with others - apply standard relaxation
(e.g., Waltz:

filtering to propagate out. The matching method
depends very much on the descriptive method for its power.

Hierarchical Symbolic Description and Matching of Time Varying Images,
ICPR82(1007-1010).
Generate various descriptions using maximal cliques and match these
cliques at the higher levels (cliques to cliques). Use relational
structures for matching. Find cliques and use to find similar
cliques in other image. Clique: completely connected subset.
Group into objects (almost always cliques) and detect similar
cliques in the image. A long formal description of relational
structures, but little on actual examples and results.
