Domain Adaptive Transfer Attack (DATA)-based Segmentation Networks for Building Extraction from Aerial Images
Semantic segmentation models based on convolutional neural networks (CNNs)
have gained much attention in relation to remote sensing and have achieved
remarkable performance for the extraction of buildings from high-resolution
aerial images. However, the issue of limited generalization for unseen images
remains. When there is a domain gap between the training and test datasets,
CNN-based segmentation models trained by a training dataset fail to segment
buildings for the test dataset. In this paper, we propose segmentation networks
based on a domain adaptive transfer attack (DATA) scheme for building
extraction from aerial images. The proposed system combines the domain transfer
and adversarial attack concepts. Based on the DATA scheme, the distribution of
the input images can be shifted to that of the target images while turning
images into adversarial examples against a target network. Defending
adversarial examples adapted to the target domain can overcome the performance
degradation due to the domain gap and increase the robustness of the
segmentation model. Cross-dataset experiments and the ablation study are
conducted for the three different datasets: the Inria aerial image labeling
dataset, the Massachusetts building dataset, and the WHU East Asia dataset.
Compared to the performance of the segmentation network without the DATA
scheme, the proposed method shows improvements in the overall IoU. Moreover, it
is verified that the proposed method outperforms even when compared to feature
adaptation (FA) and output space adaptation (OSA).Comment: 11pages, 12 figure
Optimisation of Mobile Communication Networks - OMCO NET
The mini conference âOptimisation of Mobile Communication Networksâ focuses on advanced methods for search and optimisation applied to wireless communication networks. It is sponsored by Research & Enterprise Fund Southampton Solent University.
The conference strives to widen knowledge on advanced search methods capable of optimisation of wireless communications networks. The aim is to provide a forum for exchange of recent knowledge, new ideas and trends in this progressive and challenging area. The conference will popularise new successful approaches on resolving hard tasks such as minimisation of transmit power, cooperative and optimal routing
Cross-modal Learning for Domain Adaptation in 3D Semantic Segmentation
Domain adaptation is an important task to enable learning when labels are
scarce. While most works focus only on the image modality, there are many
important multi-modal datasets. In order to leverage multi-modality for domain
adaptation, we propose cross-modal learning, where we enforce consistency
between the predictions of two modalities via mutual mimicking. We constrain
our network to make correct predictions on labeled data and consistent
predictions across modalities on unlabeled target-domain data. Experiments in
unsupervised and semi-supervised domain adaptation settings prove the
effectiveness of this novel domain adaptation strategy. Specifically, we
evaluate on the task of 3D semantic segmentation using the image and point
cloud modality. We leverage recent autonomous driving datasets to produce a
wide variety of domain adaptation scenarios including changes in scene layout,
lighting, sensor setup and weather, as well as the synthetic-to-real setup. Our
method significantly improves over previous uni-modal adaptation baselines on
all adaption scenarios. Code will be made available.Comment: arXiv admin note: text overlap with arXiv:1911.1267
