WebBecause of this analogy, the metric is known in computer science as the earth mover's distance. The name "Wasserstein distance" was coined by R. L. Dobrushin in 1970, after learning of it in the work of Leonid Vaseršteĭn on Markov processes describing large systems of automata [1] (Russian, 1969). Websignature and of the Earth Mover’s Distance (EMD), which we apply to color and texture in Section 5. We compare the results of image retrieval using the EMD with those obtained with other metrics, and demon-strate the unique properties of the EMD for texture-based retrieval.
