Approximate Message Passing with a Colored Aliasing Model for Variable Density Fourier Sampled Images

1 code implementation • 3 Mar 2020 • Charles Millard, Aaron T Hess, Boris Mailhé, Jared Tanner

Central to AMP is its "state evolution", which guarantees that the difference between the current estimate and ground truth (the "aliasing") at every iteration obeys a Gaussian distribution that can be fully characterized by a scalar.

1 code implementation • 4 Nov 2019 • Charles Millard, Aaron T Hess, Boris Mailhé, Jared Tanner

In response we present an algorithm based on Orthogonal AMP constructed specifically for variable density partial Fourier sensing matrices.
