Adaptive filtering for the lattice Boltzmann method

In this study, a new selective filtering technique is proposed for the Lattice Boltzmann Method. This technique is based on an adaptive implementation of the selective filter coefficient σ. The proposed model makes the latter coefficient dependent on the shear stress in order to restrict the use of the spatial filtering technique in sheared stress region where numerical instabilities may occur....

Texture characterization using 2D cumulant-based lattice adaptive filtering

In this work. we take into account the non gaussian properties of textures and we propose a new approach for their characterization based on bidimensional adaptive modelisation using higher order statistics. The 2DOLRIV (Bidimensionnal Overdetermined Lattice Recursive Instrumental Variable) algorithm allows accurate texture model estimation. Sets of ZD-AR coefficients obtained from the 2D refle...

Orthogonal lattice algorithms for adaptive filtering and beamforming

The application of matrix lookahead technique to the problem of ne-grain pipelining of Cordic based narrow-band adaptive beamforming is brieey discussed, It is then shown how the technique may be extended to broad-band adaptive beamforming which leads to the derivation of a ne-grain pipelined QR decomposition based multichannel recursive least square lattice (multi-channel QRD-LSL) algorithm. S...

Adaptive Filtering with Averaging

Adaptive ltering algorithms are considered in this work. The main e ort is devoted to improve the performance of such algorithms. Two classes of algorithms are given. The rst one uses averaging in the approximation sequence obtained via slowly varying gains, and the second one utilizes averages in both the approximation sequence and the observed signals. Asymptotic properties{convergence and ra...
