A 3D scene point cloud which stored on the server is reconstructed by (structure-from-motion) SfM technique in advance. On the other hand, the client system in tablets captures query images and sent them to the server to estimate the change area. In order to find region of change, an existing change detection method has been applied into our system. Then the server sends detection result image back to mobile device and visualize it. The result of system test shows that the system could detect change cor- rectly.展开更多

On the putpose to build the secure group communication among of a group of client users and one server, in this paper, we will present a new password-based group key agreement protocol. Our protocol will meet simplicity, efficiency, and many desired security properties.展开更多

It first puts forward the notion of “instant machine translation service" and illustrates how it is provided through client-server mode in EATS. Then this paper gives a panoramic view of the realization of Chinese-English bi-directional translation module through multi-engine strategy. The prototype of the system has been successfully demonstrated in campus net in PPP mode, with 70%～80% translation accuracy.展开更多
