Fig. 11From: Classification of wood surfaces according to visual appearance by multivariate analysis of wood feature data a Dendrogram for the boards from the analysis sample in log-sector class 1 based on the variables included in the discriminant model. The horizontal scale indicates the distance coefficient, standardized to relative numbers in the interval 0–25, while the numbers on the vertical scale indicate the identifiers of the boards. The dashed line indicates the chosen cluster solution and the corresponding groups are marked and numbered. Boards reallocated from group 2 to group 1 are indicated by the shaded box. b Compositions of single board images according to the chosen cluster solution labelled with the group numbersBack to article page
