Remote Sensing Image Registration Methodology: Review and Discussion

Abstract

Abstract Image registration is the process of overlaying two or more multi sensor or multi temporal or multi resolution images of the same scene. Image registration is very crucial preprocessing step in any remote sensing image processing application. This paper presents a brief review of evolution of different image registration methodologies with challenges involved in it. Image registration basically aligns the two images (reference and sensed image) geometrically. In the first part of this paper, classical methods will be discussed which are mainly based on area based (Intensity based) approach and feature based approach. Ample amount of work has already been done in both methods in manual and automatic manner. In the second part all recent approaches will be discussed and compared with results, on the basis of registration accuracy, number of correct correspondence. In recent studies Convolutional Neural Network with deep learning algorithms are used in combination with traditional methods to boost the overall performance.
