Overview on image registration

Integration of information for providing better usage and productivity is utmost important in todays scenario. Before collecting this information obtained from various modalities we need to align them properly and this process is called as image registration. The entire process of image registration becomes accurate if all the images have been acquainted well and contain relevant information. Registration algorithms compute transformations to set correspondence between the two images and to map them to single coordinate system. So to facilitate better understanding, this paper aims to discuss the basics of image registration its methodologies and few algorithms with their comparative analysis and this paper also has explained, referred and compared the classic as well as recent algorithms done on image registration that is, to provide a comprehensive and comparative review of the existing literature available on Image registration methods.
