Results on the real-world data. “cat” data is from DiLiGenT [33], and “wall-paper,” “coin,” and “logo” are recorded by ourselves. “GT” is the ground truth normal map, and for our own data, they are computed by photometric stereo. From left to right, surface normal maps and angular error maps of (a) ORIGINAL, (b) INSIDE, (c) BOX, (d) OPEN, (e) PIECEWISE, and (f) ITERATIVE are shown. The values show corresponding MAEs
