In dealing with large volume image data, sequential methods usually are too
slow and unsatisfactory. This paper introduces a new system employing para
llel matching in high-level recognition of 3D articulated objects. A new st
ructural strategy using linear combination. and parallel graphic matching t
echniques is presented for 3D polyhedral objects representable by 2D line-d
rawings. It solves one of the basic concerns in diffusion tomography comple
xities, i.e. patterns can be reconstructed through fewer projections, and 3
D objects can be recognized by a few learning sample views. It also improve
s some of the current methods while overcoming their drawbacks. Furthermore
, it can distinguish very similar objects and is more accurate than other m
ethods in the literature. An online webpage system for understanding and re
cognizing 3D objects is also illustrated.
