The influence of the noise on localizaton by image matching

In recent years, location information of people has been attracting a lot of attention as an element for construction of ubiquitous environment. Especially, high precision of that location information is very important in case of emergency. In order to realize such a high precision, technical challenges will be evaluation of the precision of GPS information of mobile phones and how to improve it using mobile phone camera. In this paper, we examine the performance of a developed matching method using correlation between motion picture database and still picture of mobile phone camera. In addition, the robustness of the matching method against unexpected noises due to blurring of mobile phone camera images is evaluated theoretically as well as experimentally.
