Approximate message passing with a colored aliasing model for variable density Fourier sampled images
The Approximate Message Passing (AMP) algorithm eciently reconstructs signals which have been sampled with large i.i.d. sub-Gaussian sensing matrices. However, when Fourier coecients of a signal with non-uniform spectral density are sampled, such as in Magnetic Resonance Imaging (MRI), the aliasing...
