This paper aims to classify and analyze recent as well as classic image registration techniques.Image registration is the process of super imposing images of the same scene taken at different times, location and by different sensors.It is a key enabling technology in medical image analysis for integrating and analyzing information from various modalities.Basically image registration finds temporal correspondences between the set of images and uses transformation model to infer features from these correspondences.The approaches for image registration can beclassified according to their nature vizarea-based and feature-based and dimensionalityvizspatial domain and frequency domain.The procedure of image registration by intensity based model, spatial domain transform, Rigid transform and Non rigid transform based on the above mentioned classification has been performed and the eminence of image is measured by the three quality parameters such as SNR, PSNR and MSE.The techniques have been implemented and inferred thatthe non-rigid transform exhibit higher perceptual quality and offer visually sharper image than other techniques.Problematic issues of image registration techniques and outlook for the future research are discussed.This work may be one of the comprehensive reference sources for the researchers involved in image registration.
