Matching process is divided into rough matching and fine matching. Rough matching divides the image into certain size blocks called R-block  sums the gray value of each R-block pixel  encodes the R-block according to the gray value distribution of R-block with the adjacent R-block  and matches by step between the template and each search sub-image. Then  fine matching results are obtained using phase correlation according to initial match parameters. The time complexity of the proposed method is (M2) .The new algorithm is faster than traditional algorithm by two orders of magnitude  and the speed has improved twice compared with existing sub-block coding method. Experiments demonstrate that the new algorithm is robust to the linear transformation of pixel grey value and image noise  and it also has the stability of small-angle rotation. 2009 IEEE.   Classification and counting on multicontinued fractions and its application to multi-sequences 期刊论文  iSwitch采集 Science in china series f-information sciences, 2007, 卷号: 50, 期号: 3, 页码: 351-358 作者:  Dai ZongDuo;  Feng XiuTao 收藏  |  浏览/下载：17/0  |  提交时间：2019/05/10 Multi-strict continued fractions  Multi-sequences  Linear complexity distribution
