【摘要】 本文给出了一个两级迭代体视匹配算法。算法以单个▽~2G通道输出中那些可因相似的方向连接成段的零交为匹配基元。第一级受体视Marr-Poggio内聚性的视差平滑性规则的控制,第二级由第一级的输出驱动并受体视Mayhew-Frisby形状连续性的视差连续性规则控制,从而使匹配结果具有在上述两个体视一般物理约束意义上的局部和全局一致性。文中给出了实验结果。更多还原

【Abstract】 A two-stage iterative stereo matching algorithm is proposed. Primitives used for matching are those zerocrossings from a single ▽~2G channel that form connected edges due to their similarity in sign and orientation. The first stage is controlled by a disparity smoothness rule which substantiates Marr-Poggio’s cohesiveness of the physical world. The second stage, driven by the output of the first stage, is governed by a disparity continuity rule that represents Mayhew-Frisby’s figural continuity. Therefore, the algorithm yields matches that are locally and globally consistent in the sense of the two general constraints of stereo vision mentioned above.更多还原
