La factibilidad de identificar el cilindro nudoso en imágenes de tomografía computarizada de rayos X (TC) de trozas podadas de pino radiata (Pinus radiata D. Don), fue evaluada utilizando un método de clasificación supervisada basado en Redes Neuronales Artificiales (RNA). El proceso de clasificación consideró también la identificación de la zona libre de defectos y nudos. Treinta trozas podadas de pino radiata fueron escaneadas en un escáner médico multi-slice de rayos X, donde las imágenes TC resultantes fueron obtenidas cada 5 mm. Un total de 270 imágenes TC fueron clasificadas utilizando la técnica Redes Neuronal Artificial y los mapas temáticos resultantes,...
