    摘要: A computer-implemented method for automatic image registration includes providing a previously aligned image pair, extracting a first number of samples of features from the previously aligned image pair, and extracting a second number of samples of features from an observed image pair. The method further includes determining a Euclidean minimum spanning tree of a union set of the samples of features from the previously aligned image pair and the observed image pair, determining a similarity measure of the observed image pair based on the Euclidean minimum spanning tree, estimating a gradient of the similarity measure, wherein a gradient estimate is used to update transformation parameters applied to register the observed image pair, and outputting a registration of the observed image pair, wherein the registration of the observed image pair is one of displayed and stored on a storage media.
