Fig. 5From: Four-dimensional measurement of root system development using time-series three-dimensional volumetric data analysis by backward predictionDiscriminator for overlapping. a Based on the vector node coordinates, blocks with size 17 × 17 × 17 voxels were cropped as positive and negative training data. The white arrowheads indicate faint root segments. b Convolutional neural network of the discriminator. Conv3D: 3D convolution, BN, batch normalization. c Fine-tuning of the discriminator model for each rootBack to article page
