To overcome the real-time and robust problem of visual tracking, a visual tracking algorithm based on a fusion of multi cue and particle filter was proposed. Firstly, the integrating formula was transmuted on the framework of particle filter base on multi-cues which integrated multi-cues based on cues rather than feature points so that it could be used for parallel computing. Secondly, the EM algorithm...
In view of the traditional image edge detection method easily lead to the disadvantage such as burr and discontinuous, use LVQ neural network to detect the digital image edge. By extracting and calculating the median characteristics, directional information characteristics and Krisch operator direction characteristics of each sample image point, generate the neural network training set and train the...
A two-step physically consistent procedure is proposed to exploit COSMO-SkyMed (CSK) synthetic aperture radar (SAR) data acquired in the incoherent dual-polarization PingPong mode. The first step, which deals with land/sea discrimination, is accomplished in a robust and effective way by exploiting the inherent peculiarities of the CSK PingPong mode. Hence, a dual-polarization scattering model that...
This paper considers the problem of robust H∞ filtering for uncertain discrete time-delay systems with stochastic perturbation. The model mentioned above is a particular case of the general time-delay systems for its stochastic state matrices. The problem to be addressed is the design of a filter that guarantees mean-square asymptotic stability and a prescribed H∞ performance level of the filtering...
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...
