This paper focuses on the Direction of arrival(DOA) tracking problem in dynamic environments where each source signal is modeled as a Gaussian process with time-varying mean and unknown covariance. In the presence of ...
Based the Variational Bayes expectation-maximization (VBEM) algorithm, a low complexity semi-blind Bayesian iterative receiver with joint signal detection and channel tracking is proposed for MIMO-OFDM systems over ...
Bayesian modeling method and slice analysis techniques show good effect in cycle-accurate power analysis of combinational circuit. In this paper, we use virtual signal logical depth assignment to resolve the problem t...
In large-scale IP-based communication sys- tems, faults are often caused by multiple factors of uncer- tainty, so bow to locate the root causes of these faults quickly and precisely plays a key role in network man- ag...
RFID technologies attract more attention for its good performance in many applications. Indoor location based on active RFID technologies provides an approach with a high performance to price ratio, which further expa...

Vessel analysis in medical images is important both for diagnostic and intervention planning purposes, especially, a three-dimensional representation of vasculature can be extremely important in image-guided neurosurg...
Dense optical flow schemes are challenged by the presence of motion boundaries. In state of the art optical flow approaches, over-smoothing of motion boundaries accounts for most of the error. A new optical flow estim...
