基于局部-全局的航空影像语义分割方法

A Local-Global Approach to Semantic Segmentation in Aerial Images

Alina Elena Marcu

摘要:

航空图像通常是在光照条件差的情况下拍摄的,包含低分辨率的物体,很多时候被其他物体遮挡。在这一领域,视觉上下文可能有很大的帮助,但仍然有很少的论文,考虑在航空图像理解的上下文,仍然是一个开放的问题,在计算机视觉。我们提出了一种双流深度神经网络,它沿着两条独立的路径处理信息。我们的模型学习以互补的方式将局部和全局外观结合起来,从而形成一个强大的分类器。我们测试了我们的双流网络在航空图像中的建筑物分割的任务,并获得了最先进的马萨诸塞州建筑物数据集的结果。我们研究了局部外观与较大场景的相对重要性,以及它们在三个新建筑物数据集上的组合性能。我们清楚地证明了视觉背景与深度神经网络结合用于航空图像理解的有效性。

英文摘要:

Aerial images are often taken under poor lighting conditions and contain low resolution objects, many times occluded by other objects. In this domain, visual context could be of great help, but there are still very few papers that consider context in aerial image understanding and still remains an open problem in computer vision. We propose a dual-stream deep neural network that processes information along two independent pathways. Our model learns to combine local and global appearance in a complementary way, such that together form a powerful classifier. We test our dual-stream network on the task of buildings segmentation in aerial images and obtain state-of-the-art results on the Massachusetts Buildings Dataset. We study the relative importance of local appearance versus the larger scene, as well as their performance in combination on three new buildings datasets. We clearly demonstrate the effectiveness of visual context in conjunction with deep neural networks for aerial image understanding.
