Aligning Raw Image to Real-time Coordinate System

Pattern matching is a technique in which the location of a particular place is found by comparing its raw image with the image present in the database. It is used to check the presence of certain structure in an image. It is done between the reference image and database images sequentially pixel by pixel. Today's applications require more of georefrencing techniques like GIS and other geographic control framework. In this paper, we provide an overview of the prototype being developed for georefrencing for GIS using pattern recognition and data mining techniques. Our system utilizes various algorithms to reduce the impact of disturbances in images using affine and asymmetric transformations by considering the following assumptions: 1. Only spatial datasets from different sources are considered. 2. A minimum threshold resolution of images is required which is determined in advance. 3. We perform pattern matching on point data by using FFT algorithm.
