DESCRIPTION (provided by applicant): A fundamental "problem" of visual perception concerns the recovery of the three-dimensional (3D) environment from two-dimensional retinal images. What are the relevant stimulus attributes that determine perception of 3D shape and how does the visual system integrate multiple sources of information to arrive at perceptual "solutions". The overarching goal of the proposed research is to link two topics of vision science, cue combination and perceptual bistability, which have addressed these issues. The study of cue combination aims to characterize how cues of differing reliability are integrated to determine perception. The study of perceptual bistability involves determining the factors that influence fluctuating visual awareness. The present proposal is built on the idea that perceptual bistability represents a case in which cue combination transpires dynamically. A series of psychophysical and computational experiments will examine cue combination for bistable 3D structure-from-motion (SFM). The specific goals of the present study are: a) to examine the interaction between motion, luminance proximity, and retinal disparity on the perception of bistable, 3D-SFM and b) to develop a model to account for cue combination in bistable SFM.

描述（由申请人提供）：视觉感知的基本“问题”涉及从二维视网膜图像中恢复三维（3D）环境的问题。确定3D形状感知的相关刺激属性是什么？视觉系统如何集成多个信息来源以达到感知“解决方案”。拟议的研究的总体目标是将视力科学，提示组合和感知性的两个主题联系起来，这些主题解决了这些问题。提示组合的研究旨在表征如何整合不同可靠性的提示以确定感知。对感知双重性的研究涉及确定影响视觉意识波动的因素。目前的提议建立在以下想法的基础上，即感知性双重性代表了一种动态提示的情况。一系列的心理物理和计算实验将检查Bistable 3D结构（SFM）的提示组合。本研究的具体目标是：a）检查运动，亮度接近性和视网膜差异之间对BISTABLE的感知的相互作用，3D-SFM和B）开发一个模型来说明Bistable SFM中的提示组合。
