摘要:

最近的图像记忆研究揭示了视觉特征,使通用图像,物体图像或面部照片难忘。然而,一个清晰的理解和可靠的估计自然场景的记忆仍然是难以捉摸的。在本文中,我们提供了一个尝试回答:“究竟是什么使自然场景难忘”。具体来说,我们首先建立LNSIM,一个大规模的自然场景图像记忆数据库(包含2,632幅图像和记忆注释)。然后,我们挖掘我们的数据库,调查如何低,中,高层次的手工制作的功能影响自然场景的记忆。特别地,我们发现场景类别的高级特征与自然场景的记忆性相当相关。因此,我们提出了一种基于深度神经网络的自然场景记忆性(DeepNSM)预测器,它利用场景类别。最后,通过实验验证了DeepNSM的有效性。

英文摘要:

Recent studies on image memorability have shed light on the visual features that make generic images, object images or face photographs memorable. However, a clear understanding and reliable estimation of natural scene memorability remain elusive. In this paper, we provide an attempt to answer: "what exactly makes natural scene memorable". Specifically, we first build LNSIM, a large-scale natural scene image memorability database (containing 2,632 images and memorability annotations). Then, we mine our database to investigate how low-, middle- and high-level handcrafted features affect the memorability of natural scene. In particular, we find that high-level feature of scene category is rather correlated with natural scene memorability. Thus, we propose a deep neural network based natural scene memorability (DeepNSM) predictor, which takes advantage of scene category. Finally, the experimental results validate the effectiveness of DeepNSM.
