タイトル: Hierarchy processing with graphs

概要:
Hierarchical data analysis is useful and became very popular in image
processing recently. The theory of hierarchical image representations have
been well studied in Mathematical Morphology, and it provides a useful
framework to treat objects or regions in digital images taking into account
theirs scales and inclusion relations. In this talk, we first explain that
such hierarchies can be represented by edge-weighted graphs. Thanks to this
graphical framework for hierarchies, some hierarchical problems are
re-written as re-weighting edge-weighted graphs if they can be considered
as problems of transforming/modifying hierarchies. We show how to make such
re-weighting efficiently for
(1) hierarchizing image segmentation algorithms, and
(2) removing non-significant regions in hierarchical
segmentation/clustering.
