The dimensional changes vary across the web and influence, e.g., the surface and compression properties of the paper; they also complicate the control of the paper machine. In this article, a robust method for estimating the relative shrinkage profile is presented. The method is based on a one-dimensional recording of the imprints from the forming fabric, using a fluorescence technique. The recording is transformed into a time-frequency spectrum, on which three different frequency estimators have been evaluated. In simulations on synthetic data and measurements on paper profiles the estimator that maximizes the correlation energy showed the most robust and accurate performance of the methods evaluated, even at a low signal-to-noise ratio.</p> http://dx.doi.org/10.1117/1.1567260 http://hh.diva-portal.org/smash/record.jsf?searchId=1&pid=diva2:237394 1475 5 Optical Engineering: The Journal of SPIE Journal Paper 1467 Estimating the relative shrinkage profile of newsprint 42 2003 2016-09-30T20:40:32Z 2457662.3614815 Estimating the relative shrinkage profile of newsprint 500 0 plainlist list 1 [[:Publications:Estimating the relative shrinkage profile of newsprint]] Estimating the relative shrinkage profile of newsprint# QUERYbb5f32b3af61f6e946fa244c6ab02abb 500 [2,"smw-datavalue-property-restricted-annotation-use","Publisher"] Estimating the relative shrinkage profile of newsprint# ERR6c155b5d70b69ddb590b4f2e73389c2a 500 [2,"smw-datavalue-property-restricted-annotation-use","Author"] Estimating the relative shrinkage profile of newsprint# ERRe24f17e090c98448f3de99d03182b7b6
