Image Registration: A Simplified Review
Main Article Content
Abstract
From the past few years, Image registration has become an emerging and hot topic for researchers. Due to the global need for low computation, less time consuming, and good quality image mapping methods has caused an image registration technique alive in multiple application areas. Image registration is the method, in which the pixels or control points of one image are superimposed on the other image. The image which is superimposed is called reference image and the image upon which superimposition process is done is called target image. The input images are reference images and sensed images. By processing these images through image registration algorithms, the target images are created. During this process, the concentration is on various methods of mapping parameters. Basically image registration is of two types: Area based and Feature based. Area based works on the intensity of image and feature based is based on feature points or objects of image. Image registration has wide scope in medical field and research. This paper presents a review on basic image registration and its techniques.
