WebJul 2, 2024 · Earth Mover’s Distance. Specified with method="emd" in getColorDistanceMatrix().. The earth mover’s distance or Wasserstein metric measures the distance between two distributions as a transport cost – essentially, what is the minimum cost of transforming one distribution into the other? It takes into account both spatial …
WebThe biggest challenge in implementing a correct EMD is the fact that a naive solution will not scale well with the size of points, both for time and memory.

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 region is the image's domain, and the total amount of light (or ink) is the "dirt" to … 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.
