From: An improved method for the removal of ring artifacts in high resolution CT imaging
1. Identify the target region Ω from the ring location of Type 1. |
2. Set the iteration index k = 0. |
3. Identify the fill front δ Ωk, i.e., contour of the target region Ωk. |
4. Compute priorities P(p) for Ψ p ∈ δ Ωk. |
5. Find the patch Ψ p with maximum priority, i.e., for |
6. Find the exemplar Ψ q ∈ Φ that minimizes d(Ψ p , Ψ q ). |
7. Copy the image data from Ψ q to Ψ p . |
8. Update C(p). |
9. Increase k by 1 for next iteration. |
10. Check whether Φk= ϕ. If yes then exit. Otherwise go back to step 3. |
