Image registration is very hot topics in the field of research from last two decades. It has a lot of applications in different field of medical imaging, remote sensing, image re-targeting etc. It is a process of aligning two or more images into one coordinate system that taken at different times, from different sensors, or from different viewpoints. The purpose of this book is to provide a comprehensive review of the existing works available on image registration. Finally I proposed a new feature based image registration method where used edge as image feature. I believe that it will be a useful document for students, academicians, researchers and others who want to work on image registration technique regardless for specific applications.
