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 WebSep 6, 2024 · The Earth Mover’s Distance is the minimum amount of work involved, where “amount of work” is the amount of earth you have to move multiplied by the distance you have to move it. The EMD can also be shown to be equal to the area between the two empirical CDFs. The EMD is a good tool for distributions with long tails.
