2014-02-21 13:23:10 -0500 | asked a question | Python: CalcEMD2 error with cost matrix I am trying to use CalcEMD2 with a custom cost matrix instead of one of the standard metrics. I followed the documentation and tried the following inputs to CalcEMD2: pre_sig1 = in1[..., None]/np.sum(in1) pre_sig2 = in2[..., None]/np.sum(in2) sig1 = cv.fromarray(np.require(np.float32(pre_sig1), requirements='CA')) sig2 = cv.fromarray(np.require(np.float32(pre_sig2), requirements='CA')) pre_cost = np.rad2deg(np.arccos(np.dot(vertices.T, vertices))) pre_cost[np.isnan(pre_cost)] = 0 cost = cv.fromarray(np.float32(pre_cost)) EMD = cv.CalcEMD2(sig1, sig2, cv.CV_DIST_USER, cost_matrix = cost) With this, I get the error: Only one of cost matrix or distance function should be non-NULL in case of user-defined distance This doesn't seem to make sense to me since I didn't give it a distance function and the default distance function input is None. Is this my mistake or a bug? |
