双目对应是研究单目视觉如何 在正常的双目视觉中，图像被正确融合，创建了一个 深度感。在自然景观中，通常有相当大的 关于内部局部元素的双目匹配的歧义性 每一个单目半图像。在过去的三年里，我们已经 使用简单的重复图案(墙纸立体图)来探索 控制人体立体匹配的规则。立体匹配 一长的水平行点的长度可以描述如下： 匹配粗略要素，例如行中的边或间隙 第一。在深度位置之间插入的平面 分配给这些粗略要素，然后指导匹配 中介点。这种插补的机制是什么？ 匹配？ 拟议的研究将解决以下问题：1) 立体声系统是否使用明确的匹配(边缘) 由粗略的空间滤波器检测来加权众多 通过精细空间过滤器选择性地检测潜在匹配？2) 不同空间中的相对对比度有什么作用 带宽在检测到的匹配的相对权重中起作用 由粗和细空间滤光片？3)亮度和 方位在立体匹配中也是重要的维度吗？4)如果 立体匹配是基于局部相关的 单目半像，其大小和视差范围是多少 这次行动？我们能在许多深度找到信号的证据吗？ 使用适应范式的飞机？ 最后一系列实验将检验两者之间的关系 对差异的增量判断(增量d/d)和 单眼距离增量判断(增量S/S) 确定当代模式的超视力是否可以推广 视差域也是如此。

Binocular correspondence is the study of how the monocular images are correctly fused in normal binocular vision, creating a sense of depth. In natural scences, there is usually considerable ambiguity about the binocular matching of local elements within each monocular half-image. For the past three years, we have used simple repetitive patterns (wallpaper stereograms) to explore the rules which control human stereo matching. Stereo matching of a long horizontal row of points can be described as follows: coarse features, such as edges or gaps in the row, are matched first. A plane interpolated between the positions in depth assigned to these coarse features then guides the matching of the intervening points. What is the mechanism of this interpolated matching? The proposed research will address the following questions: 1) Does the stereo system use the unambiguous matches (the edges) detected by coarse spatial filters to weight the numerous potential matches detected by fine spatial filters selectively? 2) What role does the relative contrast within different spatial bandwidths play in the relative weighting of the matches detected by coarse and fine spatial filters? 3) Are brightness and orientation also important dimensions in stereo matching? 4) If stereo matching is based on local cross-correlation of the monocular half-images, what is the size and disparity range of this operation? 5) Can we find evidence for signals in many depth planes using an adaptation paradigm? A final series of experiments will examine the relationship between incremental judgments of disparity (delta d/d) and incremental judgments of monocular distance (delta s/s) to determine if contemporary models of hyperacuity can be extended to the disparity domain as well.
