Complex Visual Information Processing from Real-World Environments

我们周围的世界在不断变化，我们必须跟上这种变化。无论是开车还是在客厅里找钱包，我们的视觉系统都必须能够处理接收到的信息，并整合记忆中的相关信息。这个项目旨在调查潜在的感知和认知过程，使我们能够在如此高的水平上表现。在一系列的实验中，两个主要的过程将被解决：最初的快速处理，在不到一眼的时间内描述一个场景的特征，以及随后的探索（当我们环顾四周时），以获得有用的信息。对于每一个过程，我和我的学生将研究哪些类型的信息是最重要的，信息是如何更新的，以及以前的知识如何影响我们看待新信息的方式。这项调查的结果将扩展我们对视觉系统如何在复杂环境中发挥作用的基本知识，并可应用于开发人工系统来成功管理复杂的视觉信息（例如，为特定目标搜索监视图像或按意义分类图像）或开发程序来帮助处理特殊人群（例如，多动症，自闭症或老年人）的复杂视觉信息。

The world around us constantly changing and we have to keep up with that change. Whether it is driving in a car or searching for your wallet in the living room, our visual system has to be able to manage the incoming information and integrate relevant information from our memories. This project is aimed at investigating the underlying perceptual and cognitive processes that allow us to perform at such a high-level. In a series of experiments, two main processes will be addressed: the initial rapid processing that characterizes a scene in less than a single glance and the subsequent exploration (as we look around) that is oriented towards useful information. For each of these processes, my students and I will investigate what types of information are most important, how information is updated, and how previous knowledge affects how we see new information. The results of this investigation will expand our basic knowledge of how the visual system functions in complex environments and can be applied to developing artificial systems to successfully manage complex visual information (e.g., searching surveillance images for a specific target or sorting images by meaning) or towards the development of programs to help processing of complex visual information in special populations (e.g., ADHD, autism or older adults).
