Abstract
We apply the method of projections onto convex sets (POCS) to recover a signal or image from nonuniform samples and prior knowledge. Both iterative and one-step algorithms to implement POCS are furnished. We discuss our results in relation to the recent work by Sauer and Allebach [
IEEE Trans. Circuits Syst. CAS-34,
1497 (
1987)], who considered the same problem from a different point of view.
