为了观察和理解视觉世界，我们每秒将目光从一个位置转移到另一个位置大约三次。凝视方向的这些快速变化是由称为扫视的快速眼球运动引起的。视觉信息仅在注视期间、扫视之间的静止期间获取。图片的主动视觉搜索是主动扫描视觉环境以在干扰物中寻找特定目标或提取其含义的过程。本文讨论了显着性、公开注意力和自然图片扫描的认知模型，该模型揭示了人类在主动的现实世界场景观看过程中凝视控制如何运作的神经计算机制。
To view and understand the visual world, we shift our gaze from one location to another about three times per second. These rapid changes in gaze direction result from very fast eye movements called saccades. Visual information is acquired only during fixations, stationary periods between saccades. Active visual search of pictures is the process of active scanning of the visual environment for a particular target among distracters or for the extraction of its meaning. This article discusses a cognitive model of saliency, overt attention, and natural picture scanning that unravels the neurocomputational mechanisms of how human gaze control operates during active real-world scene viewing.
