Restoration quality of motion-blurred image is highly dependent on the evaluation accuracy of the motion blur parameter. The motion blur direction and extent parameters can be determined by a single image without any prior knowledge. A linear motion blur parameter identification method, which is based on the cepstrum domain obtained from the intentional restored image, is proposed in this paper. With...
A robust and delay-optimized network coding strategy, which is suitable for unicast streaming over multihop packet-lossy networks, is proposed in this paper. The proposed network coding strategy jointly uses systematic network coding technique with delay-constrained limited hop-by-hop feedback to achieve a better tradeoff between end-to-end delay and robustness. Simulation results demonstrated that...
Spectrum sensing is one of the most important components for the establishment of cognitive radio (CR) system. The traditional spectrum sensing technology is to detect that a band of frequencies is occupied or not by the primary user of that band at the appointment time and location. However, with multi-antenna technologies, e.g. beamforming, multiple users can be multiplexed into the same channel...
