"Topological Image Analysis and Reeb Graph Representations for Plant Phenotyping";
Talk: 1st Viennese Plant Phenotyping Workshop,
This paper discusses the use of topological image
analysis to derive characteristics needed in plant phenotyping.
Due to certain features of root systems (deformation over time,
overlaps of branches in a 2D image of the root system) a topolog-
ical analysis is needed to correctly derive these characteristics.
The advantages of such a topological analysis are highlighted
in this paper and root phenotyping is presented as a new
application for computational topology. Characteristics used in
plant phenotyping that can be derived from root images using
methods of topological image analysis are further presented. A
Reeb graph based representation of root images is shown as
an example for such a topological analysis. Based on a graph
representation a new, normalised representation of root images
