1. Introduction
The rapid development of Computers and Internet technology has given birth to a new computing model-Pervasive Computing. Ubiquitous computing is a way that can calculate on when and where, as long as necessary, can access the required information on some devices. Ubiquitous computing brings convenience to the people, at the same time it also brings new challenges to the data-processing technology[1][2]. As the image information get in the environment of ubiquitous computing is very complex, including multi-platform, multi-temporal, multi-sensor, multi-resolution images, and large-scale, high-precision, real-time multi-source remote sensing data obtained by using optical, infrared, radar remote sensing and other optical measurement system, in order to meet real-time requirements, the problem how to fusion the image data from multi-sensor rapidly and effectively has become urgent[3].
