A root portion is represented as an edge (e couple of vertices) in the graph and is associated to different types of properties e.g. diameter. Recording the whole architecture necessitates a recursive pathway to be followed throughout the root system, with information about each link and segment being recorded at each stage of the measurment. The connection between two segments of the same root a… text/html 2011-02-16T11:39:03+01:00 lionel http://www.archiroot.org.uk/doku.php/navigation/architools?rev=1297852743&do=diff1297852743 How to build your own Rhizotron Camera This page gives a short description of how to build your own Rhizotron Camera using webcams.

It consist fundamentally of a generic data structure (multiscale graph representation) and elementary methods or operations to both query and modify such objects (e.g get the neighbour of a cell or modify the concentration of its constituents). The behaviour and properties of each entity in the structure (vertex, wall, cell ...) can be controlled through user specified models, using python scri… text/html 2010-02-23T10:57:36+01:00 lionel http://www.archiroot.org.uk/doku.php/navigation/balloonplugin?rev=1266919056&do=diff1266919056 An ImageJ plugin that allows the segmentation off cell wall boundaries from microscopy images. Author: Lionel Dupuy Download You can find the java class files [here]. The plugin is functional but still under development. Description This ImageJ plugin has been developed to extract cell architectures from live imaging datasets. It uses a physical “balloon inflation” algorithm for finding the cell boundaries from RGB images
