摘要: This paper presents an enhancement to the recent framework of histogram aggregation [1], that enables improve matching accuracy while preserving a low computational complexity. The original algorithm uses fronto-parallel support window for cost aggregation, which leads inaccurate results in presence significant surface slant. We address problem by considering pre-defined set discrete orientation hypotheses window. It is shown single hypothesis Disparity Space Image usually representative large interval possible 3D slants, and handling slant disparity space has advantage avoiding visibility issues. also propose fast recognition scheme volume selecting most likely aggregation. experiments clearly prove effectiveness approach.
