In this paper we describe some of the research issues and challenges in image-based location awareness and navigation. We will describe two systems being developed at Purdue University as testbeds for our ideas. The main system architecture combines image processing, mobility, wireless communication, and location awareness. We will describe two fundamental scenarios for using images to aid in mobile navigation problems. The first provides the ability to use a locally acquired image to determine the identity of an object, for example a building, as one roams in an area. The second problem is the use of images in a database to aid in vehicle navigation. The solution to these problems use location information, such as GPS signals, to compare and search location-annotated images in a database. We believe location information can improve the accuracy in image database search.
