Ligniﬁcation of wood ﬁbres has important consequences to the paper production, but its exact effects are not well understood. To correlate exact levels of lignin in wood ﬁbres to their mechanical properties, lignin autoﬂuorescence is imaged in wood ﬁbre cross-sections. Highly ligniﬁed areas can be detected and related to the area of the whole cell wall. Presently these measurements are performed manually, which is tedious and expensive. In this paper a method is proposed to estimate the degree of ligniﬁcation automatically. The method is evaluated manually by an expert. Beside some difﬁculties segmenting cells that do not conform to our model, there was a highly signiﬁcant correlation between the two methods.
