Classification of Wood Species Frequently Used for Modern and Ancient Buildings Utilizing Near-Infrared Spectroscopy with Multivariate Analysis and Enhancement of Its Generalization Performance

Near-infrared spectroscopy enables identification of previously inseparable wood species by the observation of their anatomical features by optical microscopy and through the detection of subtle differences of chemical components between wood species. This research verified whether the combination of Near-Infrared spectroscopy, multivariate analysis and feature selection method can discriminate the anatomically similar and important softwood species used as building materials, (cid:9479)(cid:9516)(cid:9509)(cid:9521)(cid:9509)(cid:9513)(cid:9511)(cid:9533)(cid:9524)(cid:9509)(cid:9526)(cid:9517)(cid:9527)(cid:9444)(cid:9523)(cid:9510)(cid:9528)(cid:9529)(cid:9527)(cid:9509) and (cid:9496)(cid:9516)(cid:9529)(cid:9518)(cid:9523)(cid:9524)(cid:9527)(cid:9517)(cid:9527) spp., and (cid:9496)(cid:9527)(cid:9529)(cid:9515)(cid:9509)(cid:9444)(cid:9527)(cid:9517)(cid:9513)(cid:9510)(cid:9523)(cid:9520)(cid:9512)(cid:9517)(cid:9517)
