WebNov 1, 2000 · We investigate the properties of a metric between two distributions, the Earth Mover's Distance (EMD), for content-based image retrieval. The EMD is based on the minimal cost that must be paid to transform one distribution into the other, in a precise sense, and was first proposed for certain vision problems by Peleg, Werman, and Rom. WebThe EMD is defined as the minimum amount of work needed to change one signature into the other. The notion of "work" is based on the user-defined ground distance which is …

WebThe Earth Mover’s Distance (EMD) [29] is a cross-bin distance that addresses this alignment problem. EMD is de-fined as the minimal cost that must be paid to transform one histogram1 into the other, where there is a “ground dis-tance” between the basic features that are aggregated into the histogram. The EMD as defined by Rubner is a met- WebYet, such approach suffers from poor out-of-distribution (OOD) generalization to new types of images (e.g., when a query face is masked, cropped or rotated) not included in the training set or the gallery. Here, we propose a re-ranking approach that compares two faces using the Earth Mover's Distance on the deep, spatial features of image patches.
