Earth mover's distances
Webearth mover distance using n-bin histogram: Using Masking-> roi, a region of interest in image 1 is specified. With Masking-> {roi 1, roi 2}, the intersection of roi 1 and roi 2 on the overlapped images is used. Predefined ImageDistance metrics are symmetric and non-negative. However, some distances may not satisfy the triangle inequality.

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 EMD-based similarity analysis (EMDSA) is an important and effective tool in many multimedia information retrieval and pattern recognition applications. However, the computational cost … See more An early application of the EMD in computer science was to compare two grayscale images that may differ due to dithering, blurring, or local deformations. In this case, the … 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 See more The EMD can be computed by solving an instance of transportation problem, using any algorithm for minimum-cost flow problem, e.g. the network simplex algorithm. The Hungarian algorithm can be used to get the solution if … 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
