From: Four-dimensional measurement of root system development using time-series three-dimensional volumetric data analysis by backward prediction

Fig. 6

A test case of backward prediction. Time-series X-ray CT volumes from 7 to 27 days after sowing was used. a An example of backward prediction of a root. Node indexes (the number of nodes counted from the root tip) and scores calculated by the discriminator were plotted. The red dashed line is represented by the equation in the figure. b An example of backward prediction of all 25 roots. Node index was converted into relative length (RL) from the root tip; 0.0 indicates the full-length and 1.0 indicates the root with length 0. Each trajectory corresponded to each root. c An example of fitting for basic trajectories. A trajectory was approximated with a line having two bending points. The red dashed line is represented by the equation in the figure. d An example of fitting for overlapped trajectories. e An example of fitting for incomplete trajectories. f All 25 trajectories after approximation
