Fast Non-Iterative Image Reconstruction from Irregular 2-D DFT Frequency Samples


Abstract— The problem of reconstructing an image from irregular frequency samples arises in synthetic aperture radar (SAR), magnetic resonance imaging (MRI), limited angle tomography, and 2-D filter design. Since there is no 2-D Lagrange interpolation formula, this problem is usually solved using an iterative algorithm, such as POCS (Projection Onto Convex… (More)
