Abstract
In this paper, a new contribution regarding the application of principal component analysis (PCA) technique is used to detect defects in wood. For this purpose, a PCA procedure is modeled and developed accordingly. The results show that this method is applicable, appropriate and reliable for identifying defects in wood and is able to separate the clear wood from the others. In particular, in the case of wood with holes, all the squared prediction errors (SPE) were higher than their threshold while in clear wood all SPE values were less than their threshold and their values are far enough from the threshold line.
