Query: Ubiquitous WLAN/Camera Positioning using Inverse Intensity Chromaticity
  Space-based Feature Detection and Matching: A Preliminary Result   This paper present our new intensity chromaticity space-based feature
detection and matching algorithm. This approach utilizes hybridization of
wireless local area network and camera internal sensor which to receive signal
strength from a access point and the same time retrieve interest point
information from hallways. This information is combined by model fitting
approach in order to find the absolute of user target position. No conventional
searching algorithm is required, thus it is expected reducing the computational
complexity. Finally we present pre-experimental results to illustrate the
performance of the localization system for an indoor environment set-up.
