Multi-MIP-NCC method. Each tile is split along the D direction into substacks of n _slices slices. For each couple of adjacent substacks, three MIPs along the three directions are extracted from the overlapping regions. Then a 2D-NCC map is computed for each pair of homologous MIPs, so obtaining two displacements for each direction. Two reliability measures extracted from the NCC map are used to select for each direction the best of the two available displacements.
