Taking a Look at Image Registration - 3124 Words

INTRODUCTION â€Å"If we knew what it was we were doing, it would not be called research, would it?† - Albert Einstein (1879 - 1955) An image is a 2 dimensional representation of a 3 dimensional scene. A Digital Image is a graphical representation of an object. Digital Image Processing abbreviated as DIP is the manipulation of digital image by a processor. Image Registration is one of the techniques used in Digital Image Processing. Registration refers to merging and fusion of 2 or more data. Image Registration is a fundamental step in all image analysis tasks in which we find mapping for each and every pair of points in two or more different images. The images of a same scene are taken from different viewpoints, from different sensors or sometimes images taken at different times are also geometrically aligned in this process. Virtually all large systems which evaluate images require the registration of images, or a closely related operation, as an intermediate step. Registration can be performed either manually or automatically. In manual method human operators manually select corresponding features in the images to be registered. In order to get reasonably good registration results, an operator has to choose a considerably large number of feature pairs across the whole images, which is not only tedious and wearing but also subject to inconsistent and limited accuracy. Thus, there is a natural need to develop automated techniques that require little or no operator supervision.Show MoreRelatedDonald Trump : Attack On Muslims848 Words   |  4 Pagesthat we have faced in past decades.
