Top panels: Image of the giant elliptical galaxy NGC1316 (center of the image) devouring its small northern neighbor. The image shows the radio emission associated with this encounter superimposed on an optical image. The radio emission was imaged using the very large array in New Mexico (Image courtesy of NRAO/AUI and Uson). The image size is N = 256 × 256. Bottom panels: MRI image of a brain from the BRAINIX database. From left to right: original image; complex magnitudes of the reconstructed images from m = 0. 4N measurements without chirp modulation; complex magnitudes of the reconstructed images from m = 0.4N measurements with chirp modulation.
