  • Method of classifying and discerning wooden materials
    Patent number: 9164029
    Abstract: A score of each of multiple pieces of reflection spectrum information included in a population is calculated using a first second principal component loading acquired by a principal component analysis, and a first group is classified based on the calculated score. Then, a score of each of multiple pieces of reflection spectrum information included in the population is calculated using a second second principal component loading acquired by a principal component analysis on a second population in which the reflection spectrum information of the first group is not included, and a second group is classified based on the calculated score. By performing a second principal component analysis using the second population, the second group can be accurately classified based on minute characteristics of each type of material included in the reflection spectrum information and the classification can be performed with a high accuracy.
