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. http://robotics.stanford.edu/~scohen/research/emdg/emd-defn.html WebAug 26, 2024 · From matrix T, we can see that the transport plan that we choose is move 0.2\in \ {x_1\} to \ {x_2\} so that they can be totally same. The EM belief divergence of belief function of m_1 and m_2 is 0.2. It is the same as using Jousselme et al.’s distance (Jousselme et al. 2001) to calculate which is also equal to 0.2. can of ham building
