：图像匹配是图像处理中的一项重要技术，在许多领域都有广泛的应用。简单地说，它就是找到两幅不同图像之间的

空间位置关系。对一种衡量图像之间相似性的推土机距离EMD 度量做了介绍，提出了一种基于EMD 度量的图像匹配方法。

实验结果表明，运用此种技术进行图像匹配相对一些其它的图像匹配方法有更好的效果。-Abstract：Image matching is considered as an important technology in image processing, and it has lots of applications. Simply put,

its goal is to find out the spatial relationship between two different images. The conception of earthmover s distance (EMD) is introduced,

which can weigh comparability between two images, then a method is constructed to match image based on EMD. Experimental results

indicate that image matching using this algorithm has good performance, when it is compared with other algorithms.
