]在SIFT局部特征的基础上,扩大了SIFT局部特征描述子,构造了半全局信息的背景环,并将背景环的互信息引入到相似性计算.实验结果表明,该方法与SIFT影像匹配算法相比,有效地提高了匹配的正确率,且对旋转图像的特等匹配具有一定鲁棒性;与全局配准算法相比较,提高了一倍以上的计算效率

This paper expands the SIFT local feature descriptors and constructed semi-global background loop.This makes the similarity distance measure rely on the effect of local characteristics,but also on the constraints of semi -global background loop.Experimental results show that,compared with the SIFT image matching algorithm,the algorithm can eliminate the wrong matching points,and it can exhibit a certain robustness for rotating the image feature matching.Compared with global registration algorithm,the efficiency of proposed algorithm can was more than double.
