WebAug 19, 2024 · In general, you can treat the calculation of the EMD as an instance of minimum cost flow, and in your case, this boils down to the linear assignment problem: Your two arrays are the partitions in a bipartite graph, and the weights between two vertices are your distance of choice. WebB. Earth Mover’s Distance The earth mover’s distance (EMD) is a metric which grew out of the optimal transport (OT) literature initiated by Monge [20]. The EMD has recently been increasingly used in a variety of applications such as image and histogram comparison [21], [22], as well as for sparse inverse problems [23]–[25]. Intuitively,

WebThis is an implementation of the Earth Movers Distance, as described in . The EMD computes the distance between two distributions, which are represented by signatures. The signatures are sets of weighted features that capture the distributions. The features can be of any type and in any number of dimensions, and are defined by the user.
