a Dendrogram for the boards from the validation sample within log-sector class 2 (boards with vertical grain). 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. b Compositions of single board images according to the chosen cluster solution labelled with the group numbers
