说明：  针对sift特点应用到了配准算法里去，并且可应用与可见光与红外光的配准中去
(In this paper, SIFT( Scale Invariant Feature Transform) feature, which has shown great success in computer vision, is introduced into image registration in remote sensing. In addition, we also p roposed a feature matching app roach based on the specific characteristic of the remote sensing imagery.)
