| Abstract: | Sub-pixel image registration is required in many applications.In this paper,firstly recent sub-pixel registration algorithms as well as classical algorithms are classified into three categories: interpolation based method,extension of phase correlation and method that formulates the problem as an optimization problem.Basic theories,performance characteristics,and recent improvements of the three methods are presented in detail.Secondly,the reviewed methods are evaluated in some criterions,factors affecting performance are analyzed.And lastly future development is discussed. |

| Keywords: | image registration sub-pixel phase correlation interpolation optimization problem |
