WebThe Earth Mover's Distance (EMD) is a distance measure between discrete, finite distributions. y = { (y 1 ,u 1 ), (y 2 ,u 2 ), ..., (y n ,u n) }. The x distribution has an amount of mass or weight w i at position x i in RK, i=1,...,m, while the y distribution has weight u j at position y j, j=1,...,n. An example pair of distributions in R2 is ... 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 $${\textstyle d}$$). Instead of assigning one distribution to the set of points, we can cluster them and represent the point set in … See more The EMD can be computed by solving an instance of transportation problem, using any algorithm for minimum-cost flow problem, … See more An early application of the EMD in computer science was to compare two grayscale images that may differ due to dithering, … See more • C code for the Earth Mover's Distance (archived here) • Python implementation with references • Python2 wrapper for the C implementation of the Earth Mover's Distance See more Some applications may require the comparison of distributions with different total masses. One approach is to allow for a partial match, where dirt from the most massive distribution is rearranged to make the least massive, and any leftover "dirt" is discarded at no … See more EMD-based similarity analysis (EMDSA) is an important and effective tool in many multimedia information retrieval and pattern recognition applications. 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. The name "earth movers' … See more
