Earth mover’s distance 代码
http://robotics.stanford.edu/~rubner/papers/rubnerIjcv00.pdf Webcolor perception. Defining a distance between two dis-tributions requires first a notion of distance between the basic features that are aggregated into the distribu-tions. We call this distance the ground distance.For instance, in the case of color, the ground distance mea-sures dissimilarity between individual colors. Fortu-
