A Nonlocal Method with Modified Initial Cost and Multiple Weight for Stereo Matching

Table 2

Comparison of the four nonlocal algorithms (MST [15], ST-1 [17], ST-2 [17], and the proposed method) with Middlebury datasets and the standard of benchmark. The error threshold is set to 1 and three regions (nonocc, all, and disc) are used to evaluate the performance of the methods. Our proposed method exhibits the best accuracy in every region.

nonocc	all	disc	nonocc	all	disc	nonocc	all	disc	nonocc	all	disc
MST	5.73	1.50	2.18	8.02	0.42	0.85	5.02	5.95	10.89	14.15	3.14	8.68	7.94
ST-1	5.66	1.73	2.52	9.22	0.47	0.71	4.56	6.11	10.88	14.53	2.47	8.28	7.11
ST-2	5.18	1.35	2.00	7.29	0.42	0.69	5.27	5.17	9.95	12.95	2.49	7.90	6.62
