Figure 8

Columns: column (i) shows texture images of portions of hulls; column (ii) shows reconstructed images resulting from the proposed reconstruction scheme; column (iii) shows reconstructed images resulting from Tsai algorithm; column (iv) shows reconstructed images resulting from Han algorithm; column (v) shows defects segmented by hand, the “ground truth.” Image Rows: (a) H225, (b) H34, (c) H241, (d) H1, (e) H120, (f) H121, (g) H99, (h) H137, (i) H48, (j) H9, (k) H10, and (l) H11.
