Explicit schemes of the most important dual-space algorithms. Projections (6)[link] and (8)[link] were used for PM and PD, respectively. [\tau], [\omega], [\varphi] and [\psi] are intermediate images, [\hat{\tau}], [\hat{\omega}], [\hat{\varphi}] and [\hat{\psi}] their Fourier transforms, respectively. The schemes correspond to equations (13)[link] (CFA), 17[link] (HIO), 22[link] (AAR) and 19[link] (DM).  [article HTML]
