AB  - Root system traits are important in view of current challenges such as
AB  - sustainable crop production with reduced fertilizer input or in resource
AB  - limited environments. We present a novel approach for recovering root
AB  - architectural parameters based on image analysis techniques.
AB  - It is based on a graph representation of the segmented and
AB  - skeletonised image of the root system, where individual roots are
AB  - tracked in a fully-automated way. Using a dynamic root architecture
AB  - model for deciding whether a specific path in the graph is likely to
AB  - represent a root helps to distinguish root overlaps from branches and
AB  - favours the analysis of root development over a sequence of images.
AB  - After the root tracking step, global traits such as topological
AB  - characteristics as well as root architectural parameters are computed.
AB  - Analysis of neutron radiographic root system images of Lupinus
AB  - albus grown in mesocosms filled with sandy soil results in a set of root
AB  - architectural parameters. They are used to simulate the dynamic
AB  - development of the root system and to compute the corresponding root
AB  - length densities in the mesocosm.
AB  - The graph representation of the root system provides global
AB  - information about connectivity inside the graph. The underlying root
AB  - growth model helps to decide which path inside the graph is most
AB  - likely for a given root. This facilitates the systematic investigation of
AB  - root architectural traits in particular with respect to parametrisation of
AB  - dynamic root architecture models
