A novel approach, coined the Corner-Cutting method (CC, for short), is presented in this paper which affords the efficient construction of the baseline for analytical data streams. It was derived from techniques used in computer aided geometric design, a field established to produce curves and surfaces for the aviation and automobile industries. This corner-cutting technique provided a very efficient baseline calculation through an iterative process. Furthermore, a terminal condition was developed to make the process fully automated and truly non-parametric. Finally, we employed a Bezier curve to convert the iterating result into a smooth baseline solution. Compared to other iterative schemes used for baseline detection, our method was significantly efficient, easier to implement, and had a broader range of applications.
本文提出了一种新颖的方法，简称为“抄近路法”（CC），它能有效地构建分析数据流的基线。该方法源自计算机辅助几何设计中使用的技术，这一领域是为航空和汽车工业生成曲线和曲面而设立的。这种抄近路技术通过迭代过程提供了非常高效的基线计算。此外，还开发了一个终止条件，以使该过程完全自动化且真正无参数。最后，我们使用贝塞尔曲线将迭代结果转换为平滑的基线解。与用于基线检测的其他迭代方案相比，我们的方法效率显著更高、更易于实现且应用范围更广。
