“…Habite, et al (Habite et al, 2020(Habite et al, , 2022 used two neural networks to locate the pith of Norway spruce (Picea abies) timber boards to great success. The first used a conditional generative adversarial network (cGAN) (Habite et al, 2020), and the latter used a one-dimensional convolutional neural network (Habite et al, 2022). Moreover, it is difficult to estimate the location of the pith using the plastic sheet of concentric circles described by Habite, et al's (Habite et al, 2022(Habite et al, , 2020.…”
