摘要:

人类视觉科学领域的最新研究表明,人类对视觉显示器上的刺激的反应是不确定的。人们可以同时关注同一视觉输入上的不同位置。基于这些知识,我们提出了一个新的随机模型的视觉注意力,通过引入一个动态贝叶斯网络来预测人类通常集中在视频场景的可能性。该模型由4层动态贝叶斯网络组成。我们的模型提供了一个框架,模拟和结合的视觉显着性反应和认知状态的一个人来估计最可能出席的地区。基于马尔可夫链蒙特卡罗的粒子滤波器和流处理的基于样本的推理与多核处理器使我们能够估计人类的视觉注意力在近实时的。实验结果表明,我们的模型在预测人类视觉注意力方面比以前的确定性模型表现得更好。

英文摘要:

Recent studies in the field of human vision science suggest that the human responses to the stimuli on a visual display are non-deterministic. People may attend to different locations on the same visual input at the same time. Based on this knowledge, we propose a new stochastic model of visual attention by introducing a dynamic Bayesian network to predict the likelihood of where humans typically focus on a video scene. The proposed model is composed of a dynamic Bayesian network with 4 layers. Our model provides a framework that simulates and combines the visual saliency response and the cognitive state of a person to estimate the most probable attended regions. Sample-based inference with Markov chain Monte-Carlo based particle filter and stream processing with multi-core processors enable us to estimate human visual attention in near real time. Experimental results have demonstrated that our model performs significantly better in predicting human visual attention compared to the previous deterministic models.
