WebSep 29, 2009 · We present a new algorithm for a robust family of Earth Mover's Distances - EMDs with thresholded ground distances. The algorithm transforms the flow-network of the EMD so that the number of edges is reduced by an order of magnitude. As a result, we compute the EMD by an order of magnitude faster than the original algorithm, which … WebThe similarity or distance measure between Gaussian mixture models (GMMs) plays a crucial role in content-based image matching.
