  • J A Fessler, A O Hero, "Space-alternating generalized expectation-maximization algorithm." IEEE Tr. Sig. Proc., 42(10):2664-77, Oct. 1994. (IEEE Explore version) Errata: The equation immediately below eqn. (18) is unnecessary. As written it suggests we foolishly replace some of the pixel estimates with "old" values, when of course we do not. The newer version that appears in our 1995 T-IP paper is correct, and supersedes the T-SP version. The proof of Theorem 2 incorrectly states that the eigenvalues of the Gauss-Siedel matrix are real. They can be complex, so the proof only applies to cases where the maximum magnitude eigenvalue is real. (.pdf)
