Abstract:
|
In recent published papers we have presented the Extreme Vertices Model
(EVM), a concise and complete model for representing orthogonal
polyhedra. This model exploits the simplicity of its domain by
allowing robust and simple algorithms for set-membership
classification and Boolean operations that do not need to perform
floating-point operations.
A digital image is geometrically analogue to an orthogonal polyhedron
and can therefore be represented with the EVM.
In this paper we discuss the performance in terms of space occupancy
and algorithm complexity of representing digital binary images by this
model. We also present a boundary extraction algorithm of a 3D digital
image using the EVM and discuss its performance. |
