This paper describes an approach to recognize buildings. The characters of building such as facets, their area, vanishing points, wall histogram and a list of local features are extracted and then stored in a database. Given a new image, the facet with biggest area is compared against the database to choose the closest pose. Novel methods of cross ratio-based refinement and SVD (singular value decomposition) based method are used to increase the recognition rate, increase the number of correspondences between image pairs and decrease the size of database. The proposed approach has been performed with 50 interest buildings containing 1050 images and a set of 50 test images. All images are taken under general conditions like different weather, seasons, scale, viewpoints and multiple buildings. We obtained 100(%) recognition rate.
