Curvature is a useful low level surface descriptor of wood fibres in {3D} micro-CT images of paper and composite materials. It may for instance be used to differentiate between the outside and the inside (lumen) of wood fibre. Since the image acquisition introduces noise, some kind of smoothing is required to obtain accurate estimates of curvature. However, in these materials, the fibres of interest are frequently both thin and densely packed. In this paper, we show how existing methods fail to… CONTINUE READING
