VISUAL IMAGE MOTION PROCESSING IN HUMANS

我们提出了一系列人类心理物理实验来 回答两个主要领域的问题。基本情况是什么？ 图像运动处理的机制是什么？ 功能优势。 在机制方面，我们专注于迭代水平的 分析，询问来自基本运动子单元的信号是如何 结合时间、空间和空间尺度的信息。我们的 主要的心理物理任务将是辨别方向 运动、测量对比度阈值、信噪比 阈值和最小位移阈值(Dmin)。一 研究将获得对搬家僵硬感知的评级 算出来了。 就运动处理的功能优势而言，我们将 研究3个方面：首先，我们将测量定位的精度 使用宽度辨别任务对运动定义的边界进行识别。 第二，我们将调查情感深度敏感度，询问 是否与单眼运动敏感度有关； 是否可以通过单克隆运动适应来改变它；以及 它是否可以得到一个旋转式的运动刺激的支持 没有单眼运动信息。第三，我们将调查 运动处理如何在重新校准 从视差信号中提取深度。

We propose a series of human psychophysical experiments to answer questions in two broad areas. What are the basic mechanisms of image motion processing and what are the functional benefits. In terms of mechanism, we focus at an itermediate level of analysis, askig how the signals from elementary motion subunits combine information over time, space, and spatial scale. Our primary psychophysical task will be to discriminate the direction of motion, measuring contrast thresholds, signaltonoise ratio thresholds, and minimum displacement thresholds (Dmin). One study will obtain ratings of the perceived rigidity of moving figures. In terms of the functional benefits of motion processing, we will study 3 areas; first we will measure the precision of localization of motiondefined boundaries using a width discrimination task. Second, we will investigate motionindepth sensitivity, asking whether it can be related to monocular motion sensitivity; whether it can be altered by monoclonal motion adaptation; and whether it can be supported by a cyclopean motion stimulus which has no monocular motion information. Third, we will investigate how motion processing might play a role in recalibrating the depthfromdisparity signal.
