Motion Blur Prior
We have proposed a novel methodology for generating priors that favor motion blur. Priors play an important role of regularizers in image deblurring algorithms. Image priors are frequently studied and many forms were propos...

Approximating Clustered Millimeter Wave Vehicular Channels by Sparse Subband Fitting
, few attempts of low-complexity approximation of such channels exist. Prior results structures and are efficiently approximated as sparse channels. We thereby render sparse tapped delay line model fits possible. In this co...

Weighted decomposition in high-performance lattice-Boltzmann simulations: are some lattice sites more equal than others?
-Boltzmann simulations of realistic sparse problems to the exascale. Here we analyse-Boltzmann simulation environment, when applied to sparse domains. Both techniques are applied prior to partitioning our domain using a thi...

Assessments of Implementation of the Minimum Degree Ordering Algorithms
The minimum degree ordering is one of the most widely used algorithms to preorder a symmetric sparse matrix prior to numerical factorization. There are number of variants which try to reduce the computational complexity of the origi...

Fast Bayesian JPEG Decompression and Denoising With Tight Frame Priors
a posteriori probability framework by iterative optimization algorithms. Prior knowledge about an image is usually describednby the l1 norm of its sparse domain representation. For many problems, if the sparse domain forms...
