Webearth_movers_distance (dist1, dist2, distances=None) [source] ¶ Compute the Earth Mover’s Distance (EMD) between dist1 and dist2. The EMD is the least amount of “probability mass flow” that must occur to transform dist1 to dist2. Parameters. dist1 (Distribution) – The first distribution. dist2 (Distribution) – The second distribution. WebCompute the first Wasserstein distance between two 1D distributions. This distance is also known as the earth mover’s distance, since it can be seen as the minimum amount of “work” required to transform u into v, where “work” is measured as the amount of distribution weight that must be moved, multiplied by the distance it has to be moved.

Websignature and of the Earth Mover’s Distance (EMD), which we apply to color and texture in Section 5.
