摘要:

无监督域适应一直是跨数据分布迁移语义分割模型的有效方法。同时,基于大规模视觉语言模型的近期开放词汇语义场景理解方法在开放集设置下十分有效,因为它能够学习多样的概念和类别。然而,由于缺乏跨视角几何建模,这些已有方法难以泛化到不同的相机视角。目前,分析跨视角学习的研究十分有限。为解决这一问题,我们提出了一种新颖的无监督跨视角自适应学习方法,用于在语义场景理解中对跨视角的几何结构变化进行建模。首先,我们针对未配对数据引入了新颖的跨视角几何约束,以对跨相机的图像和分割掩码中的结构变化进行建模。其次,我们提出了一种新的基于测地流的关联度量,以高效测量跨相机视角的几何结构变化。第三,我们引入了一种新颖的视角条件提示机制,以增强开放词汇分割网络在跨视角自适应学习中的视角信息建模。在不同的跨视角自适应基准上的实验表明了我们的方法在跨视角建模中的有效性,证明与先前的无监督域适应和开放词汇语义分割方法相比,我们实现了最先进的性能。

英文摘要:

Unsupervised Domain Adaptation has been an efficient approach to transferring the semantic segmentation model across data distributions. Meanwhile, the recent Open-vocabulary Semantic Scene understanding based on large-scale vision language models is effective in open-set settings because it can learn diverse concepts and categories. However, these prior methods fail to generalize across different camera views due to the lack of cross-view geometric modeling. At present, there are limited studies analyzing cross-view learning. To address this problem, we introduce a novel Unsupervised Cross-view Adaptation Learning approach to modeling the geometric structural change across views in Semantic Scene Understanding. First, we introduce a novel Cross-view Geometric Constraint on Unpaired Data to model structural changes in images and segmentation masks across cameras. Second, we present a new Geodesic Flow-based Correlation Metric to efficiently measure the geometric structural changes across camera views. Third, we introduce a novel view-condition prompting mechanism to enhance the view-information modeling of the open-vocabulary segmentation network in cross-view adaptation learning. The experiments on different cross-view adaptation benchmarks have shown the effectiveness of our approach in cross-view modeling, demonstrating that we achieve State-of-the-Art (SOTA) performance compared to prior unsupervised domain adaptation and open-vocabulary semantic segmentation methods.
