摘要:

随着双摄像头在最近发布的智能手机中的普及,已经提出了越来越多的超分辨率(SR)方法来增强立体图像对的分辨率。然而,缺乏高质量的立体数据集限制了这一领域的研究。为了便于训练和评估新的立体SR算法,在本文中,我们提出了一个名为Flickr1024的大规模立体数据集,其中包含1024对高质量的图像,涵盖了不同的场景。我们首先介绍了数据采集和处理流水线,然后比较了几个流行的立体数据集。最后,我们进行了跨数据集实验,以研究我们的数据集带来的潜在好处。实验结果表明,与KITTI和Middlebury数据集相比,我们的Flickr1024数据集可以帮助处理过拟合问题,并显着提高立体SR方法的性能。Flickr1024数据集可在线获取:https://yingqianwang.github.io/Flickr1024。

英文摘要:

With the popularity of dual cameras in recently released smart phones, a growing number of super-resolution (SR) methods have been proposed to enhance the resolution of stereo image pairs. However, the lack of high-quality stereo datasets has limited the research in this area. To facilitate the training and evaluation of novel stereo SR algorithms, in this paper, we present a large-scale stereo dataset named Flickr1024, which contains 1024 pairs of high-quality images and covers diverse scenarios. We first introduce the data acquisition and processing pipeline, and then compare several popular stereo datasets. Finally, we conduct crossdataset experiments to investigate the potential benefits introduced by our dataset. Experimental results show that, as compared to the KITTI and Middlebury datasets, our Flickr1024 dataset can help to handle the over-fitting problem and significantly improves the performance of stereo SR methods. The Flickr1024 dataset is available online at: https://yingqianwang.github.io/Flickr1024.
