WebToday we talked about Earth Mover Distance (EMD) which we mentioned in the previous lecture. Given two sets A and B of points in a metric space, EMD(A,B) is the cost of the minimum cost bipartite matching between points of A and B, i.e. sum of the cost of corresponding distances. We shall focus on 2-dimensional A and B. We can embed this … WebThe earth mover’s distance (EMD) has been used extensively in elds such as image processing, computer vision and statistics [13, 15, 27, 17]. E.g. EMD has been widely used in image retrieval problems [21]. In this paper, we present a new method to approximate the EMD. This method is simple to implement and simple to parallelize.
