Investigation of Color Constancy for Ubiquitous Wireless LAN/Camera Positioning: An Initial Outcome
This work addresses indoor positioning for mobile phone users, but it appears incremental as it builds on existing color constancy and hybridization techniques without introducing major innovations.
The paper tackled the problem of indoor positioning by investigating color constancy schemes in a hybrid Wireless LAN and camera system for mobile phones, resulting in a method that eliminates the need for conventional searching algorithms to reduce computational complexity, with preliminary results presented for performance evaluation.
This paper present our color constancy investigation in the hybridization of Wireless LAN and Camera positioning in the mobile phone. Five typical color constancy schemes are analyzed in different location environment. The results can be used to combine with RF signals from Wireless LAN positioning by using model fitting approach in order to establish absolute positioning output. There is no conventional searching algorithm required, thus it is expected to reduce the complexity of computation. Finally we present our preliminary results to illustrate the indoor positioning algorithm performance evaluation for an indoor environment set-up.
