Approximate Message Passing With a Colored Aliasing Model for Variable Density Fourier Sampled Images
The Approximate Message Passing (AMP) algorithm efficiently reconstructs signals which have been sampled with large i.i.d. sub-Gaussian sensing matrices. Central to AMP is its “state evolution,” which guarantees that the difference between the current estimate and ground truth...
