摘要:

本文介绍了BigEarthNet,这是一个新的大规模多标签Sentinel-2基准存档。BigEarthNet由590,326个Sentinel-2图像块组成,每个图像块都是i)10 m波段的120 x120像素; ii)20 m波段的60 x60像素; iii)60 m波段的20 x20像素。与大多数现有的档案不同,每个图像块都由多个土地覆盖类别(即,2018年CORINE土地覆盖数据库(CLC 2018)提供的多标签。BigEarthNet比现有的遥感(RS)档案大得多,因此在深度学习的背景下用作训练源要方便得多。本文首先讨论了现有档案的局限性,然后描述了BigEarthNet的属性。在RS图像场景分类问题的框架中获得的实验结果表明,与在ImageNet(这是计算机视觉中非常流行的大规模基准存档)上预训练的最先进的CNN模型相比,在BigEarthNet上训练的浅层卷积神经网络(CNN)架构提供了更高的准确性。BigEarthNet开辟了有前途的方向,以推进业务遥感应用和研究在大规模的哨兵-2图像档案。

英文摘要:

This paper presents the BigEarthNet that is a new large-scale multi-label Sentinel-2 benchmark archive. The BigEarthNet consists of 590,326 Sentinel-2 image patches, each of which is a section of i) 120x120 pixels for 10m bands; ii) 60x60 pixels for 20m bands; and iii) 20x20 pixels for 60m bands. Unlike most of the existing archives, each image patch is annotated by multiple land-cover classes (i.e., multi-labels) that are provided from the CORINE Land Cover database of the year 2018 (CLC 2018). The BigEarthNet is significantly larger than the existing archives in remote sensing (RS) and thus is much more convenient to be used as a training source in the context of deep learning. This paper first addresses the limitations of the existing archives and then describes the properties of the BigEarthNet. Experimental results obtained in the framework of RS image scene classification problems show that a shallow Convolutional Neural Network (CNN) architecture trained on the BigEarthNet provides much higher accuracy compared to a state-of-the-art CNN model pre-trained on the ImageNet (which is a very popular large-scale benchmark archive in computer vision). The BigEarthNet opens up promising directions to advance operational RS applications and research in massive Sentinel-2 image archives.
