An Algorithm for Spline Interpolation Curve with the Shortest Perpendicular Distance

Zhang Shiqiang  
When we use Douglas-Peuker algorithm to line data compression, We select critical points using a Perpendicular distance tolerance. Existing interpolation techniques often fail to restore thd critilcal points.In this paper, a new algorithm for spline interpolation curve by werghted average has been put forwad. This method not only keep the curve through the critical points but also with the shortest perpendicular distance, thus restore the critical points. Then tenso-friction is proposed to this methd,and It's equationesare given out.
