Webthe discrete version of the EMD. Indeed, the term “Earth Mover’s distance” seems to have been coined in [21] by researchers studying the discrete case, so the assumption of discrete domains is often implicit to its usage. One of the only known non-discrete cases with an explicit formula is if = R and D(x;y) = jx yj. Then W( ]; [) = Z F](y ... WebJul 27, 2014 · A novel method for computing the earth mover's distance (EMD) between probability distributions on a discrete surface is introduced and a class of smooth …
WebWe propose a fast algorithm for the calculation of the Wasserstein-1 distance, which is a particular type of optimal transport distance with transport cost homogeneous of degree one. Our algorithm is built on multilevel primal-dual algorithms. Several numerical examples and a complexity analysis are provided to demonstrate its computational speed. On … WebAbstract We introduce a novel method for computing the earth mover’s distance (EMD) between probability distributions on a discrete surface. Rather than using a large …
