Abstract
This paper describes a novel image registration method that combines log-polar transform and SIFT to recover similarity transformations (rotation/scale/translation). We extracts SIFT feature points in the two images firstly. Then, we use threshold Euclidean distance to coarsely match the feature points. After that, the log-polar transform is applied to compute the rotation and scale parameters. And we can obtain the translation parameter by the location relationship of the feature points.
