Relaxed ordered-subset algorithm for penalized-likelihood image restoration
S Sotthivirat, JA Fessler - JOSA A, 2003 - opg.optica.org
The expectation-maximization (EM) algorithm for maximum-likelihood image recovery is
guaranteed to converge, but it converges slowly. Its ordered-subset version (OS-EM) is used …
