Earth movers' distance
http://robotics.stanford.edu/~rubner/papers/rubnerIjcv00.pdf WebAug 13, 2024 · So, in this blog, we will discuss the Earthmover’s distance also known as Wasserstein metric which is more suitable for finding distance or similarity between the distributions. This concept was first introduced by Gaspard Monge in 1781, in the context of transportation theory ( Wikipedia ). Let’s discuss the main concept behind this.

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, e.g. the network simplex algorithm 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.
