Chromatic Individuality of Fir (Abies alba Mill.) Compression Wood

Abstract

The encountered difficulties in fir’s normal structure wood delimitation from compression wood, due to numerous intermediary forms, have been motivated the research of better efficiency indicators for defect investigation. The colorimetric investigations in CIELab chromatic space, presented in current paper, had as object the felled fir wood from Brasov surrounding areas. The discriminatory aptitude of colour components is statistically proved, especially for yellow colour and reflectance. There are also analysed the quantitative relations between the chromatic indexes values from characterized structure type perspective.
