Spatial and Temporal Interpolation in Visual Object Perception

视觉上感知到的大多数物体都被其他物体部分遮挡 物体;然而人类观察者准确地检测到统一性， 在大多数情况下，物体的边界。 还有其他 在没有边界的情况下感知边界的现象 局部视觉信息，如虚幻的轮廓和一些 透明现象。 在所有这些案件中， 感知到的物体边界被插在物理上， 指定的边缘。 本项目将处理以下各种情况： 边界插值，测试和改进最近提出的 统一理论，更一般地说，试图指定 插值发生的条件。 具体目标 包括两个和三个边缘插值测试- 三维显示器产生方法的发展 随机显示，并制定各种措施， 评估边界感知，包括感知报告 和非语言的措施。 这项工作将产生影响， 来理解人类对物体的感知， 计算机视觉系统中的边界检测。

Most objects perceived visually are partly occluded by other objects; yet human observers accurately detect the unity and boundaries of objects under most circumstances. There are other phenomena in which boundaries are perceived in the the absence of local visual information, such as illusory contours and some perceived transparency phenomena. In all of these cases, perceived object boundaries are interpolated between physically- specified edges. This project will address the various cases of boundary interpolation, testing and refining a recently proposed unifying theory, and more generally attempting to specify the conditions under which interpolation occurs. Specific aims include tests of edge interpolation in both two and three- dimensional displays, development of methods for generation of random displays, and development of a variety of measures for assessing boundary perception, including both perceptual report and non-verbal measures. This work will have implications both for understanding human perception of objects and for object and boundary detection in computer vision systems.
