A Survey on Landmark Recognition Techniques

While it is probable to investigate the World Wide Web (WWW) for images, there is still no best way of searching the image. Hence recognizing and modeling landmarks at world-scale is a valuable and crucial task. First of all, the looks of any given landmark vary from one observation to successive. In addition to variations as a result of entirely diverse aspects, association in illuminated amendment, external litter, and dynamic geometry of the imaging devices are alternative factors affecting the variability of the ascertained landmarks. Finally, it is generally troublesome to create use of correct 3D information in landmark recognition applications. For those reasons, it is unacceptable to use several of the object recognition techniques. Hence it is vital to investigate the various techniques of landmark recognition so that we can find out the bottlenecks and how further improvement can be possible. In this paper, we perform a survey on various landmark recognition techniques and try to build a world-scale landmark identification engine.
