Fast Regularized Reconstruction of Non-Uniformly Subsampled Partial-Fourier Parallel MRI Data
We present an adaptation of our previous fast, regularized parallel MRI reconstruction approach (LSQR-Hybrid) to encompass the reconstruction of partial-Fourier data. Reconstructi...

Regularized split gradient method for nonnegative matrix factorization
This article deals with a regularized version of the split gradient method (SGM), leading to multiplicative algorithms. The proposed algorithm is available for the optimization of...

Sparse Representation of Cast Shadows via L1-Regularized Least Squares
Scenes with cast shadows can produce complex sets of images. These images cannot be well approximated by lowdimensional linear subspaces. However, in this paper we show that the...

Collaborative Schema Construction using Regular Sequence Types
In this paper we describe an approach to build XML schemas in a collaborative way. The approach is based on computing intersection between sequences of type terms built over const...
