Why are some images easier to remember than others? Here, we review recent developments in our understanding of 'image memorability', including its behavioral characteristics, its neural correlates, and the optimization principles from which it originates. We highlight work that has used large behavioral data sets to leverage memorability scores computed for individual images. These studies demonstrate that the mapping of image content to image memorability is not only predictable, but also non-intuitive and multifaceted. This work has also led to insights into the neural correlates of image memorability, by way of the discovery of a type of population response magnitude variation that emerges in high-level visual cortex as well as higher stages of deep neural networks trained to categorize objects.
为什么有些图像比其他图像更容易被记住？在这里，我们回顾了我们对“图像可记性”的理解的最新进展，包括其行为特征、神经相关性，以及它所产生的优化原则。我们强调了使用大型行为数据集的工作，这些数据集利用了为个别图像计算的可记性分数。这些研究表明，将图像内容映射到图像可记性不仅是可预测的，而且是不可直觉的和多方面的。这项工作还通过发现高水平视觉皮层以及经过训练以分类对象的深层神经网络的更高阶段中出现的一种群体反应幅度变化类型，为图像可记性的神经相关性提供了新的见解。
