Hausdorff distance 豪斯多夫距离 python
Web式(1)称为双向Hausdorff distance,是Hausdorff distance的最基本形式; 式(2)中的h(A,B)和h(B,A)分别称为从A集合到B集合和从B集合到A集合的单向Hausdorff距离。 … Compute the directed Hausdorff distance between two 2-D arrays. Distances between pairs are calculated using a Euclidean metric. Parameters: u (M,N) array_like. Input array. v (O,N) array_like. Input array. seed int or None. Local numpy.random.RandomState seed. Default is 0, a random shuffling of u and v that guarantees reproducibility. Returns ...
