Abstract
Although the ASD-POCS algorithms using small Lp-norm (pâ¯â¤â¯0.5) priors yield a higher MTF than do the high Lp-norms, the best noise-resolution performance is achieved when p is between 0.8 and 1. The results are expected to be a reference to the choice of p in Lp-norm (0â¯<â¯pâ¯â¤â¯2) regularization.
