ON DETERMINATION OF SEGMENTATION POINTS INTERVAL AND HIGH-PRECISION RECONSTRUCTION METHOD
摘要
Abstract
For low precision of segmentation points extraction in the process of cross-sectional data reconstruction and for human-computer interaction behaviour when determining the segmentation points interval,we present a mathematical statistics principle-based method to deter-mine the segmentation points interval.First,it uses mean smoothing method to pre-process the cross-sectional data of line and spline;Second-ly,based on 3σprinciple it determines the right endpoints of segment points interval,and then based on correlation coefficient method it deter-mines the left endpoints of interval;Finally,it uses golden section method to search the optimal segmentation points within the determined in-terval.To extract the segmentation points within the determined interval can search the segmentation points from existing points,besides,it can also find more precise segmentation points among existing data points,and moreover the method of interval determination avoids the occurrence of human-computer interaction.Examples show that this method is effective in determining the interval of segment points and improves the pre-cision of cross-sectional data segmentation.关键词
