Moving human objects (or ‘strangers’ as referred here) in the background obscure the scenery in regular panorama photography. Hence this paper proposes a novel method to remove the strangers from the background of the panorama. In the proposed system the object segmentation, dynamic background inpainting, and panorama creation phases are used to compose a panorama. If the detected face data of ...

—Routing is one of the difficult issues in mobile opportunistic networks, due to the lack of global knowledge and sporadic links. Related works use a greedy strategy to forward packets, i.e., they select relays with higher/bigger quality metrics. In this paper, we study the Opportunistic Routing Protocols (ORPs) from the perspective of social network analysis. Specifically, we discuss the impa...

A new approach to establishing trust between strangers is trust negotiation, the bilateral exchange of digital credentials describing attributes of the negotiation partic...
