Image Registration Techniques: A Comprehensive Survey

This paper aims to present a overview of recent as well as classic image registration methods. Image registration is the process of overlaying images (two or more) of the same scene taken at different times, from different viewpoints, and/or by different sensors. The registration geometrically aligns two images (the reference and sensed images). The reviewed approaches are classified according to their nature (area-based and feature-based) and according to four basic steps of image registration procedure: feature detection, feature matching, mapping function design, and image transformation and resampling. Registration algorithms compute transformations to set correspondence between the two images the purpose of this paper is to provide a comprehensive review of the existing literature available on Image registration methods. Main contributions, advantages, and drawbacks of the methods are mentioned in the paper. We believe that it will be a useful document for researchers longing to implement alternative Image registration methods for specific applications.
