摘要:

视觉搜索是人类视觉系统快速感知场景的重要策略。引导搜索理论认为,全局布局或其他自上而下的场景来源在引导对象搜索中起着至关重要的作用。为了验证场景布局和区域线索在引导视觉注意中的具体作用,我们在这项工作中执行了一个心理物理实验,用眼动跟踪系统记录人类对自然场景的线条画的注视。我们收集了10名受试者从498自然图像和另外10名受试者从相应的996人标记的边界线图纸(每幅图像两个边界图)在自由观看条件下的固定。实验结果表明,在缺乏颜色、亮度等基本特征的情况下,线条画与自然图像的注视点分布具有较高的相关性。此外,与区域的基本线索相比,被试更关注线描的封闭区域,这些区域通常与场景的主导对象有关。最后,我们建立了一个计算模型,证明了在自然场景中,线画上的注视信息可以用来显着提高经典的自底向上模型的注视预测性能。这些结果支持完形特征和场景布局是指导快速视觉对象搜索的重要线索。

英文摘要:

Visual search is an important strategy of the human visual system for fast scene perception. The guided search theory suggests that the global layout or other top-down sources of scenes play a crucial role in guiding object searching. In order to verify the specific roles of scene layout and regional cues in guiding visual attention, we executed a psychophysical experiment to record the human fixations on line drawings of natural scenes with an eye-tracking system in this work. We collected the human fixations of ten subjects from 498 natural images and of another ten subjects from the corresponding 996 human-marked line drawings of boundaries (two boundary maps per image) under free-viewing condition. The experimental results show that with the absence of some basic features like color and luminance, the distribution of the fixations on the line drawings has a high correlation with that on the natural images. Moreover, compared to the basic cues of regions, subjects pay more attention to the closed regions of line drawings which are usually related to the dominant objects of the scenes. Finally, we built a computational model to demonstrate that the fixation information on the line drawings can be used to significantly improve the performances of classical bottom-up models for fixation prediction in natural scenes. These results support that Gestalt features and scene layout are important cues for guiding fast visual object searching.
