Ligniﬁcation of wood ﬁbers has important consequences tothe paper production, but its exact eﬀects are not well understood. Tocorrelate exact levels of lignin in wood ﬁbers to their mechanical proper-ties, lignin autoﬂuorescence is imaged in wood ﬁber cross-sections. Highlyligniﬁed areas can be detected and related to the area of the whole cellwall. Presently these measurements are performed manually, which is te-dious and expensive. In this paper a method is proposed to estimate thedegree of ligniﬁcation automatically. A multi-stage snake-based segmen-tation is applied on each cell separately. To make a preliminary evaluationwe used an image which contained 17 complete cell cross-sections. Thisimage was segmented both automatically and manually by an expert.There was a highly signiﬁcant correlation between the two methods, al-though a systematic diﬀerence indicates a disagreement in the deﬁnitionof the edges between the expert and the algorithm.
