Abstract

Nonuniformly spaced samples of Fourier transforms of the image are used in holography and in image transmission to reduce the number of samples required to reconstruct an acceptable image. Nonuniform sampling produces image distortion which must be corrected in different ways for noise-free samples than for noisy ones.
