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 ... Web"Earth Mover’s Distances on Discrete Surfaces."

How do you compute numerically the Earth mover

WebThe Earth mover’s distance is a distance measure between probability distributions. If we consider each probability mass function as a histogram of dirt, it is equal to the amount of work needed to optimally move the dirt of one histogram into the shape of the other. For categorical data, the “distance” between unequal symbols is unitary. Webto color and texture, and we compare the retrieval performance of the EMD with that of other distances.

WebThe Earth Mover's Distance (EMD) is a method to evaluate dissimilarity between two multi-dimensional distributions in some feature space where a distance measure between single features, which we call the ground distance is given. The EMD ``lifts'' this distance from individual features to full distributions. WebThe total amount of work done by this flow is 0.23*155.7 + 0.26*277.0 + 0.25*252.3 + 0.26*198.2 = 222.4.
