查询词典 visual acuity

To understand the basic properties, underlying mechanisms and functions of the short-term synaptic plasticity of thalamocortical visual pathway, we combined in vivo field potential recording, focal drug application technique and neuron models, to explore the short-tem synaptic plasticity of rat major thalamocortical visual pathway (from lateral geniculate nucleus to primary visual cortex) and extrageniculate pathway (from lateral posterior nucleus to primary visual cortex), as well as the role of short-term depression in the neuronal correlated firing detection.

我们结合在位场电位记录、局部加药和神经模型等方法，对不同刺激模式下大鼠丘脑皮层主要视觉通路（外侧膝状体到初级视皮层）和非主要视觉通路（膝体外通路：丘脑侧后核到初级视皮层）的短时程突触可塑性，以及短时程抑制作用对神经元同步活动检测的作用做了研究，试图了解视觉丘脑皮层突触传递短时程可塑性的基本特性、神经机制和功能。

Firstly, visual attention mechanism, visual attention computing model and the art state are introduced. Secondly, the need and importance of visual saliency in image are analyzed. In addition, the levels, extraction and measurement of visual saliency are discussed in detail. At last, open problems are put forward.

本文首先介绍了视觉注意力、视觉注意力计算模型及研究现状，其次分析了图像中引入视觉显著性的必要性和重要性，论述了图像视觉显著性的层次、显著性特征的选择及度量；最后给出了有待研究的重点问题。

In the pre-experiment stage, we analyze the colors and shapes of 135 visual illusions by Kitaoka, a Japanese scholar. The result is referenced in the formal experiment. Formal experiment includes three sub-experiments: Experiment 1 is to discuss the effect of the displacement of disjunctive center on visual illusions' movement; Experiment 2 is to discuss the effect of image layout on visual illusions' movement; Experiment 3 is to discuss the effect of color configuration on visual illusions' movement. Post-experiment stage is a repeat of formal experiment to confirm the results.

前测实验是进行日本学者北冈明佳的135幅错视动态作品之造形与色彩的分析，并将分析结果作为正式实验样本之参考；正式实验分成三个实验进行探讨，实验一在探讨分割点中心的位移对於错视图形在视觉动态上的影响，实验二在探讨图形配置对於错视图形在视觉动态上的影响，实验三在探讨色彩配置对於错视图形在视觉动态上的影响；而后测实验则是将正式实验之实验结果进行再实验，以印证正式实验之结果。
