3D pore size characterisation by means of image analysis and mathematical morphology

In this paper the sub-micrometre computer tomography (sub-μm-CT) was used in order to investigate the structure of OSB and particle board. The data obtained were analysed using mathematical morphology and image analysis in order to obtain information on the pore size distribution. The observed distributions were found to follow Γ-law. Between the pore size distribution and the local density correlations were found in this investigation; due to the inhomogeneous structure these correlations are weak for OSB; for particle board they are much better and similar as for MDF.
