Abstract
An accurate segment-based cost aggregation method is proposed in this paper. Segment-based methods can speed up the procedure according to the assumption that pixels belonging the same segment should share the same physical property. One of the most critical problems of those methods is the limited pixels within the corresponding segment. To enlarge supporting region of aggregation efficiently, we include similar adjacent segments with a fixed weight instead of a complex one. With introducing the simplified spatial weight for adjacent segments, the proposed method outperforms existing segment-based cost aggregate method[11], the Adaptive Support-weight[3], and the cross-based cost aggregation[10]. Comparing the other aspect of performance, this algorithm also speeds up the computation time by 43%.
