Abstract:
|
This paper presents a new approach to carry out erosion, dilation
and connected component labeling. We use the Extreme Vertices Model
(EVM), an orthogonal polyhedra representation, to describe binary
images and volume datasets in a very efficient way.
Our proposal does not use a voxel-based approach but deals with the
inner sections of the object. It allows to treat images and volumes
indistinctly using the same algorithm and data structure with no
overhead of memory and can be applied to manifold as well as
non-manifold data. The connected component labeling algorithm actually
detects non-manifold zones and permits to break or not the objects at
these zones by an user-specified parameter. |
