Image registration is a fundamental task in remote sensing image processing that is used to match two or more images taken, for example, at different times, from different sensors or from different viewpoints. A lot of automation has been achieved in this field but ever sprouting data quality and characteristics compel innovators to design new and/or improve existing registration techniques. In this paper, image registration methodologies are broadly classified into intensity and feature based approaches and analyzed critically.
