3-Dimensional Model of Paper Structure Using Image Analysis

Paper sheets are being split using a laminating device. The fibers in each layer are detected using image analysis. The fibers are assigned to their position in the original sheet and aggregated into seperate volume elements. The local orientation in these elements is determined in order to find correlations to phenomena like paper cockle and dimensional instability. Samples from industrial papers are examined. The other focus of the project is the measurement of the filler z-distribution in paper. Scanning electrone microscopy images are analyzed in order to determine the differences between kaolin z-distribution and calcium carbonate z-distribution.
