WebApr 1, 2012 · Earth movers distance Description The earth mover's distance (EMD) quantifies similarity between utilization distributions by calculating the effort it takes to shape one utilization distribution landscape into another Usage ## S4 method for signature 'SpatialPoints,SpatialPoints' emd (x,y, gc = FALSE, threshold = NULL,...) 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. duty free crystal discount code
