| Algorithm 2 Plaque Noise Area Detection | |
| Input:ID, npymin, npymin, mpmin | |
| Output:Stat(tid), true for noise point | |
| 1: | row search: Xsearcher (npx, ID) |
| 2: | col search: Xsearcher (npy, ID) |
| 3: | mp = npx × npy |
| 4: | ifnpx < npxmin||npy < npymin||mp < mpmin then |
| 5: | return: Stat (tid) ← true |
| 6: | else |
| 7: | return: Stat (tid) ← false |
| 8: | endif |
