Development of Image Analysis for the Measurement of Internal Properties of Coated Paper by X-Ray Microtomography, 2005 TAPPI Coating Conference
This paper reports a technique, based on analysis of X-ray micro-tomographyiμCT) images to analyze the internal
properties of coated paper through the thickness direction(ZD). The image analysis method for paper applications
using μCT have been developed by a few groups, but the method that can analyze these images to obtain the full
range of properties in detail has not been presented before.
The internal properties include formation and fiber orientation distribution through the thickness direction (ZD), as
well as ash and pore distribution in x-y- and z-directions. The image analysis technique involved many steps
including alignment, axial conversion, filtering, binarization, skeletonization and alignment. The method is applied
for analysis of two kinds of coated paper and the results provide interesting insight for papermaking and coating
process.
