In this paper, we first polygonize the scattered data points, then estimate the normal vector and curvature of each point using the local presentation of data points.

首先对获得的散乱数据点云进行多边形化，然后根据数据点局部表示对每点的法矢和曲率进行估算。

Finally, my thesis adviser in grad school has researched Russian demographics for over 30 years, including during the Brezhnev period when basic demographic indicators were state secrets (he had to painstakingly assemble estimates by laboriously pouring over specialized virology and immunology journals which had a few data points scattered throughout them).
