| Outline of Final Research Achievements |
This research quantified the spatial distribution of moisture content, density, Young's modulus, compression wood section, and microfibril angle within Cryptomeria japonica and Larix kaempferi branches using near-infrared hyperspectral imaging (NIR-HIS) and multivariate data analysis techniques. The calibration models for prediction of moisture content, density, Young's modulus and microfibril angle were developed using partial least squares (PLS) regression analysis. The PLS model for these traits showed good predictive performance. The high density compression wood could be visualized with NIR-HIS technique. Classification of softwoods and hardwoods also enabled by principal component analysis. The results presented here provide useful information for development of a novel wood sorting method.
