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. Section 6 concludes with a summary WebNov 5, 2024 · It is basically a distance between two probability distributions. It is sometimes also called the earth mover distance as it can be interpreted as how much 'dirt' you have to move to change one 'landscape' (distribution) in another. Choosing a bit of everything.

When p= 1 this is also called the Earth Mover distance. The minimizer J (which does exist) is called the optimal transport plan or the optimal coupling. In case there is an optimal transport map T then J is a singular measure with all its mass on the set f(x;T(x))g. It can be shown that Wp p (P;Q) = sup;˚ Z (y)dQ(y) Z ˚(x)dP(x)
