Image-analysis of cross section slice of sized warp by Gaussian fitting

In order to analyze the cross-sectional slice images of sized warp objectively and reduce subjective factors on the results,this paper presents an approach to analyze the gray-scale histogram of cross section slice image of sized warp by Gaussian fitting.We get the distribution of interval of sizing factors in histogram based on the components analysis about main item,sub-items and other items of the Gaussian fitting results.The spread of slurry,sizing percentage and relative radius of pulpiness distribution were calculated with 3δ principle and the normal characteristics of gray in the interval.The experimental results agree with practical values.
