In HEVC video coding, all-zero-block (AZB) detection is an efficient tool to decrease the complexity of mode decision for rate distortion optimization (RDO). Threshold based on deadzone quantization was widely used for AZB detection, and the threshold was derived according to ensemble based statistical analysis however using individual sample's parameters such as block's SATD [1] [2]. This paper proposes...
Neighbor discovery is a crucial step in the initialization of wireless ad hoc networks. When directional antennas are used, this process becomes more challenging since two neighboring nodes must be in transmit and receive states, respectively, pointing their antennas to each other simultaneously. Most of the proposed neighbor discovery algorithms only consider the synchronous system and cannot work...
