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 … In statistics, the earth mover's distance (EMD) is a measure of the distance between two probability distributions over a region D. In mathematics, this is known as the Wasserstein metric. Informally, if the distributions are interpreted as two different ways of piling up a certain amount of earth (dirt) over the region … See more Assume that we have a set of points in $${\textstyle \mathbb {R} ^{d}}$$ (dimension $${\textstyle d}$$).

However, the computational cost of EMD is super-cubic to the number of the "bins" given an arbitrary "D". … See more The concept was first introduced by Gaspard Monge in 1781, in the context of transportation theory. The use of the EMD as a distance measure for monochromatic images was described in 1989 by S. Peleg, M. Werman and H. Rom.
