In many filter applications the exact steering vector is not know, and thus, robust beamforming methods have to be used. In this contribution, an algorithm which achieves robust beamforming via target tracking is proposed. In contrast to existing approaches, the algorithm works on sparse signals with arbitrary steering vector shapes, and the parameters of the algorithm are adapted in an optimal way...
Natural images in the colour space YUV have been observed to have a non-Gaussian, heavy tailed distribution (called `sparse') when the filter ??(U)(r) = U(r) - s??N(r)?? w(Y)rsU(s), is applied to the chromacity channel U (and equivalently to V), where w is a weighting function constructed from the intensity component Y. In this paper we develop Bayesian analysis of the colorization problem using the...
This paper presents a novel framework of fast and efficient compressive sampling based on the new concept of structurally random matrices. The proposed framework provides four important features, (i) It is universal with a variety of sparse signals, (ii) The number of measurements required for exact reconstruction is nearly optimal, (iii) It has very low complexity and fast computation based on block...
