Overview of image registration

The global demand for low-computation, low-time-consuming, and high-quality image mapping methods has maintained an image registration technique alive in a variety of applications over the last few years. The practise of superimposing pixels or control points from one image on another, namely the target image and reference image, is known as image registration. The emphasis is on different methods of parameter mapping. The reference image and the sensed image are the input images. There are two forms of image registration: area-based and feature-based. Area based works with the image's intensity, while feature based works with the image's feature points or artefacts. In several implementation fields, quick and effective registration strategies are also critical. This paper provides an overview of image registration methods as well as a review.
