The Ad hoc Multicast Routing protocol (AMRoute) presents a novel approach for robust IP Multicast in mobile ad hoc networks by exploiting user-multicast trees and dynamic logical cores. It creates a bidirectional, shared tree for data distribution using only group senders and receivers as tree nodes. Unicast tunnels are used as tree links to connect(More)
PURPOSE Intensity modulated radiation therapy (IMRT) allows greater control over dose distribution, which leads to a decrease in radiation related toxicity. IMRT, however, requires precise and accurate delineation of the organs at risk and target volumes. Manual delineation is tedious and suffers from both interobserver and intraobserver variability.

This thesis describes our work towards a unified framework for automatic restoration of dirt and blotches in archive film. The framework we present here is composed of three stages, i.e. defect detection, false alarm elimination, and defect removal. First, we propose a novel probabilistic approach to detect defects in digitized archive film. An HMM is(More)
