Pyramid segmentation algorithms revisited
The main goal of this work is to compare pyramidal structures proposed to solve segmentation tasks. Segmentation algorithms based on regular and irregular pyramids are described, together with the data structures and decimation procedures which encode and manage the information in the pyramid. In order to compare the different segmentation algorithms, we have employed three types of quality mea...
متن کاملStochastic pyramid revisited
We focus in this paper on a new model for graph decimation which is based on the stochastic pyramid algorithm. In this study, we present some trends towards a better understanding of the new properties arising from the removal of the sequentiality constraint of this so-called technique. 2002 Elsevier Science B.V.

متن کاملZ-Trees: Adaptive Pyramid-Algorithms for Image Segmentation
This paper introduces a direction-sensitive and locally reorientable compact binary tree, called the Z tree, for representing digital images. A rotation operation is de ned on a subset of its node, called square nodes, to spatially reorganize the four grand children of any given square-node. The goal is to adapt the Z tree in order to produce a minimal cutset representation of homogeneous regio...

متن کاملA revision of pyramid segmentation
Dual graph contraction reduces the number of vertices and of edges of a pair of dual image graphs while, at the same time, the topological relations among the 'surviving' components are preserved. Repeated application produces a stack of successively smaller graphs: a pair of dual irregular pyramids. The process is controlled by selected decimation parameters which consist of a subset of surviv...
