Earth Mover's Distance(EMD)是由Rubner[13]等人所提出用於影像搜 寻之上,当特徵间(bin与bin)的距 可以使用ground distance求得时, 用 Earth Mover's Distance做相似 计算可以得到较好的结果.EMD与weighted quadratic distance 是cross-bin的测 方式,但是他们 主要的 同是,在weighted quadratic distanc...
EMD（earth mover distance）距离：在计算机科学与技术中，地球移动距离(EMD)是一种在D区域两个概率分布距离的度量，就是被熟知的Wasserstein度量标准。不正式的说，如果两个分布被看作在D区域上两种不同方式堆积一定数量的山堆，那么EMD就是把一堆变成另一堆所需要移动单位小块最小的距离之和。上述的...
Earth Mover s Distance，即陆地移动距离，是一种度量准则。光线变化能引起颜色直方图的漂移，引起颜色值位置发生变化，这时候一些直方图的比较匹配策略失效。EMD算法本身是一个通用的算法，它实际上度量的是怎样讲一个直方图的形状转变为另一个直方图的形状，包括直方图的部分（或全部）到一个新的位置，可以...

Earth Movers Distance was suggested by Stol falls into the corresp onding bin For instance in a greylevel histogram d is equal to one the set of p ossible grey values is split into N intervals and h is the numb er of pixels in an image that have a grey value in the i interval ...
The key idea is to consider the more general problem of com- puting distances between probability distributions supported on the mesh. In fact, our goal is to compute the gold standard of distri- butional distances, the well-known earth mover's distance (EMD). Once we have a means to ...

EMD距离即Earth Mover's Distance,是由2000年IJCV期刊文章《The Earth Mover's Distance as a Metric for Image Retrieval》提出的一种图像相似度度量方法,从文章标题也可以得知,最初EMD的概念是用于图像检索的。后来因为其各种优点,逐渐用到其他方面的相似度度量。这篇文章主要理解EMD的概念。 signature 论文... ...
