Without artifacts. (a) The NCCC values at each position on Sb when S1 is matched to Sb. The best position is Pos[S1,Sb]=6. (b) The NCCC values at each position on Sb when S2 is matched to Sb. The best position is Pos[S2,Sb]=5. (c) Stack 1 and stack 2. The dashed line shows the adjacent location. In this example, Pos[S1,Sb]−Pos[S2,Sb]=1, which indicates that there is no artifact between S1 and S2.
