%EMD (Earth Movers Distance) % e=emd(w1,w2,C) % [e,F]=emd(w1,w2,C) % w1 is the weight vector of the first signature (1 by n1) % w2 is the weight vector of the second signature (1 by n2) % C is the Cost matrix between signatures (n1 by n2) % you can compute the cost matrix depending on you features % e is the EMD distance % F is the Flow, a matrix (m by 3) in which a row contains a flow % in this order [from to amount] % This is the MATLAB mex interface to the following implementation % http://ai.stanford.edu/~rubner/emd/default.htm by Y.
