Major DIRT functionalities. a A cowpea root dataset annotated with experiment parameters and location and shared with three other members (names were replace with red bars). b The overview of the computed cowpea data set shown in (a). The computation parameters are shown along with icons of the image mask. Computed traits and entered image metadata can be downloaded as Excel compatible.csv files. c A user can visually choose the best threshold parameter to separate the root from the background. d Each of the images in the computation shown in (b) can be assessed in detail. Every image processing step can be followed visually per image and compared to the original image and the computed traits
