—Opportunistic networks are sparse multi-hop ad hoc networks in which nodes exploit any pair-wise contact opportunities to share and forward messages. The main challenge for this environment is that conventional routing schemes do not work properly. Among the existing Opportunistic Networks routing algorithms, the epidemic routing and probabilistic routing(More)
As a preprocessing step of chest Computed Tomography (CT) images, lung segmentation is significant for the diagnosis of lung disease. The traditional watershed algorithm is sensitive to the noise and has the drawback of over-segmentation problem. This paper presents a novel image segmentation method to improve Watershed segmentation algorithm with the(More)
