The paper presents a discrete variation of the Fréchet distance between closed curves, which can be seen as an approximation of the continuous measure. A rather straightforward approach to compute the discrete Fréchet distance between two closed sequences of m and n points using binary search takes time. We present an algorithm that takes time, where is the iterated logarithm.

闭合曲线的离散 Fréchet 距离
该论文提出了闭合曲线之间 Fréchet 距离的离散变化,可以将其视为连续测度的近似值。使用二进制搜索计算两个m和n点闭合序列之间的离散 Fréchet 距离的一种相当直接的方法需要时间。我们提出了一种算法时间,地点是迭代对数。
