Colour constancy feature detection and matching technique for WLAN/Camera indoor positioning system
The location determination system in a changing environment, especially in an indoor environment can be very challenging if Global Positioning System (GPS) signals are blocked. It is necessary to combine or integrate multiple sensors and positioning methods in order to provide better location determ...
