Robust adaptive beamforming based on jointly estimating covariance matrix and steering vector
In this paper, a new adaptive beamforming algorithm with joint robustness against covariance matrix uncertainty as well as steering vector mismatch is proposed. First, the theoret...

A general Bayesian algorithm for visual object tracking based on sparse features
This paper describes a Bayesian algorithm for rigid/non-rigid 2D visual object tracking based on sparse image features. The algorithm is inspired by the way human visual cortex se...

Integer fast lapped orthogonal transform based on direct-lifting of dcts for lossless-to-lossy image coding
Integer lapped orthogonal transforms (LOTs) are vital technologies for the unification of lossless and lossy image coding, called losslessto-lossy image coding. In this paper, we...

Robust changepoint detection based on multivariate rank statistics
We introduce a novel statistical test for unsupervised detection of changepoints in multidimensional sequences of temporal observations. The test statistic is based on a multivari...
