IMAP-TV2 Algorithm for Solving (16)
| Input: P =I0 ⊙ e−Ytilde;, I0i | |
| 1: | Initialize μ, b, ρ, Λ = 0 and Y = max{ln(I0) − ln(P), 0} |
| 2: | while not convergence do |
| 3: | Update Q by Algorithm 1. |
| 4: | Update Y by Algorithm 2. |
| 5: | Update Z by (25) |
| 6: | Update b by (28) |
| 7: | Update Λ by Λ+ = Λ + μ(D2Y − Z) |
| 8: | Let μ = ρμ |
| 9: | end while |
| Output: the denoised scan Y | |
