提出了一种用于模拟自下而上视觉注意的新时空模型。它是根据人类视觉系统 (HVS) 的许多重要特性构建的。本文重点介绍模型的架构及其性能。鉴于自下而上视觉注意的空间模型已经被定义[O. Le Meur et al., 2004]，时间维度的描述更加准确。与从眼睛跟踪装置收集的人类注视进行定性和定量比较。从前者来看，预测的质量被认为非常好，而后者说明人类注视的最佳预测器由所有视觉特征（消色差、彩色和运动）的总和组成。
A new spatio-temporal model for simulating the bottom-up visual attention is proposed. It has been built from numerous important properties of the human visual system (HVS). This paper focuses both on the architecture of the model and on its performances. Given that the spatial model of the bottom-up visual attention has already been defined [O. Le Meur et al., 2004], the temporal dimension is more accurately described. A qualitative and quantitative comparison with human fixations collected from an eye tracking apparatus is undertaken. From the former, the quality of the prediction is deemed very good whereas the latter illustrates that the best predictor of the human fixation consists of the sum all visual features (achromatic, chromatic and motion).
