Classification based survey of image registration methods

Image registration technique is useful for variety of applications ranging from surveillance to image mosaicing where task is to match two or more pictures taken, for example, at different times, from different sensors, or from different viewpoints. This paper is an attempt to make a survey of image registration techniques and provides overall source of recent as well as classic research. Scope of this paper is to explain, refer and compare researches done in last decade, on image registration. Classification of registration process is done on various basis including applications, dimensions and essential ideas. Each step of registration process is explained but more attention is given to feature matching and feature detection. Also an attempt is made to explain transformation and re-sampling involved in registration, thereby making this paper a single source (for future researchers) of process and research involved in the field of Image Registration.
