In the new video coding paradigm, Wyner-Ziv (WZ) video coding, or lossy coding of video with decoder side information (SI), SI is involved not only in the decoding of the quantized source, but also in the reconstruction process, so the quality of SI is a key factor to the performance of a WZ video codec. In this paper, an approach to SI estimation for WZ video coding is proposed. It is based on motion...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
