Image Registration

8.1 Introduction

Image registration is the process of overlaying two or more images of the same scene taken at different times, from different viewpoints and/or by different sensors. By image registration, the reference and the sensed images are aligned [88, 89 and 90]. Image registration is an important step in all image processing fields that require the integration of information from multiple observations into a single image.

Image registration is a fundamental inverse problem in imaging. It represents a critical pre-processing step to many modern image processing tasks such as multichannel image restoration, image super-resolution (SR), and video compression. Image registration is a specific case of the ...
