FIGURE 10: Cross stereogram

Fusion of the left and center images (by "uncrossing") produces the percept of a black horizontal bar in front of a vertical bar (as indicated on the bottom left). Fusion of the center and right images produces the percept of a vertical bar in front of a horizontal bar (bottom right). For cross-fusers the reverse depth relationships are perceived.
