RhizoVision Crown: An Integrated Hardware and Software Platform for Root Crown Phenotyping

Figure 3

RhizoVision Analyzer for automated batch analysis of root crown images (a). The software has a user interface (a) for selecting input and output folders, choosing image threshold levels before analysis, classifying root diameter ranges, and saving options. The segmented image (b) and feature image (c) are optionally generated by the RhizoVision Analyzer. The feature image shows a blue convex polygon that is fit around the entire root system for extraction of the convex area. The boundary and skeletal pixels are shown in red and the distance transform is shown in green. The “holes” or the background image patches that were disconnected due to the overlapping of foreground pixels are randomly colored for distinction.
