This paper presents a new representation for root images
based on Reeb graphs. The representation proposed captures lengths and
distances in root structures as well as locations of branches, numbers of
lateral roots and the locations of the root tips. An analysis of root images
using Reeb graphs is presented and results are compared to ground truth
measurements. This paper shows, that the Reeb graph based approach
not only captures the characteristics needed for phenotyping of plants,
but it also provides a solution to the problem of overlapping roots in
the images. Using a Reeb graph based representation, such overlaps can
be directly detected without further analysis, during the computation of
the graph.
