The Relationship between near Infrared Spectroscopy and Surface Color of Eight Rosewoods

Abstract:

Rosewood is a kind of precious wood. Accurate wood species identification is a time consuming task for highly trained human experts. The development of cost effective techniques for automatic wood identification is a desirable goal. Wood color is one of the crucial factors to identify wood species. The color parameters (CIE L*, a* and b*) of eight rosewoods and the relationship between near infrared spectroscopy (NIR) and the color parameters were investigated in this paper. The results showed there was significant correlation between near infrared spectroscopy and color parameters. The correlation coefficients between laboratory-measured and NIR-predicted L*, a* and b* values were 0.93~0.99. The results will be helpful to develop a new method of rosewood identification through near infrared spectroscopy coupled with multivariate data analysis.
