STEREOACUITY AND BINOCULAR CORRESPONDENCE

双目对应是研究如何单目 图像在正常的双眼视觉中正确融合， 深度感。 在自然界中，通常有相当多的 内的局部元素的双目匹配的模糊性 每个单眼半图像。 在过去的三年里，我们 使用简单的重复模式（墙纸立体图）来探索 控制人体立体匹配的规则。 立体匹配 一个长的水平行的点可以描述如下： 粗要素（如行中的边或间隙）将被匹配 先 在深度位置之间插入的平面 分配给这些粗糙特征的，然后引导匹配的 插入点。 这种内插的机制是什么 匹配吗 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） 由粗空间滤波器检测，以加权 通过精细空间滤波器选择性地检测潜在匹配？ （二） 不同空间中的相对对比起什么作用 带宽在检测到的匹配的相对权重中起作用 通过粗和细空间滤波器？ 3)是亮度和 方向也是立体匹配的重要维度吗？ 4)如果 立体匹配是基于局部互相关的 单目半像，什么是大小和视差范围 这次行动？ 5)我们能在很多深度找到信号的证据吗 飞机使用适应范例？ 最后一系列的实验将检验 差异的增量判断（Δ d/d）与 单眼距离的增量判断（delta s/s）， 确定当代超敏模型是否可以扩展 到视差域。

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.
