The single matching phase SMP approach is described in the [1] and details concerning the SIMD implementation can be found in [2].
The bidirectional matching (BM) approach is described in [3].
The "Tsukuba", "Map", "Sawtooth", "Venus", "Barn1", "Barn2", "Bull" and "Poster" stereo pairs are available in [4 ] and used in [5].
