In this paper we propose a patch based approach for tracking points on planar regions. Once an adequate number of points to track is chosen from an image, their environments are locally matched without any further keypoint extraction. Starting from the result of the previous image as a prediction, the resulting homography is refined by repeating the matching process with patches transformed according to the last result.

Enhanced-positioning systems are able to support the acquisition of accurate location information using wireless technology other than the Global Positioning System (GPS). These systems have the potential to supplement GPS where GPS is unreliable. In particular, enhanced-positioning systems can provide location information for navigational support and Location based Services (LBS) indoors and in dense urban canyons and natural environments with extreme relief. The emergence of LBS and the widespread adoption of GPS-based navigation systems are largely a result of the accuracy with which GPS devices can determine location. The purpose of this study is to validate Wireless internet access points (WiFi APs) for determining location. This research follows three steps: 1. establish the accurate WiFi position for APs;2. plot transects of signal strength for APs;and 3. interpolate a campus signal strength map from transect data for the University of Saskatchewan campus and validate that map. This is the first step towards the development of a non-GPS location system that can provide accurate location in a fashion that can be seamlessly integrated with GPS.
