Based on corner detection algorithm,image registration is for any pixel of an image and centering on its circular area USAN.The process makes the image border pick-up with its outline tracking an integral whole.Corner information among images can be achieved by scanning along the circle.After the corners of different frames of the same scene are detected,the matching corner pairs between these frames can be found.Based on these pairs,initial image registration parameters can be estimated.Use iterative process to improve image registration accuracy.Experiment proved that,this algorithm has no limitation on rotation degree between images,and image registration precision is high while the computation load is small.
