Fig. 2From: Four-dimensional measurement of root system development using time-series three-dimensional volumetric data analysis by backward predictionWorkflow with backward prediction. Segmentation: CT volumes were converted to RSA-segmented volumes by RSAvis3D. Projection views of 3D RSA-segmented volumes are shown. Vectorization: RSA-segmented volumes were vectorized to an RSA vector. Projection views of 3D RSA-segmented volumes merged with 3D vectors. RSA vector is drawn in green. Backward prediction: The ochre arrows indicate the direction of the backward predictionBack to article page
