Earth Mover’s Distance The earth mover’s distance (EMD) is a metric which grew out of the optimal transport (OT) literature initiated by Monge [20]. The EMD has recently been increasingly used in a variety of applications such as image and histogram comparison [21], [22], as well as for sparse inverse problems [23]–[25]. Intuitively, chipcharapWebThe morphing distance is a measure which computes the cost of changing one shape to another. For example, ﬁgure 7 shows how to change a cup to a doughnut through a series of small transformations. This measure also satisﬁes the triangle inequality. One example of a morphing distance is the Earth Mover’s Distance. The problem grant hill draft year
