自动估计照片的创建日期的问题在过去很少得到解决。在本文中，我们介绍了一种新的数据集日期估计在野外的任务，预测收购年的图像在1930年至1999年期间捕获的。与以前的工作相比，该数据集既不限于彩色摄影，也不限于特定的视觉概念。该数据集包含从Flickr抓取的100多万张图像，包含大量不同的动机。此外，我们分别提出了回归和分类的两种基线方法，依赖于最先进的深度卷积神经网络。实验结果表明，这些基线已经优于未经训练的人的注释上级。
The problem of automatically estimating the creation date of photos has been addressed rarely in the past. In this paper, we introduce a novel dataset Date Estimation in the Wild for the task of predicting the acquisition year of images captured in the period from 1930 to 1999. In contrast to previous work, the dataset is neither restricted to color photography nor to specific visual concepts. The dataset consists of more than one million images crawled from Flickr and contains a large number of different motives. In addition, we propose two baseline approaches for regression and classification, respectively, relying on state-of-the-art deep convolutional neural networks. Experimental results demonstrate that these baselines are already superior to annotations of untrained humans.
