摘要:

最近,立体匹配基准的记录不断被端到端视差网络打破。但是这些深度模型的领域自适应能力相当差。为了解决这个问题,我们提出了一种新的域自适应管道称为AdaStereo,旨在对齐深度立体匹配网络的多级表示。与以往的自适应立体匹配方法相比,AdaStereo实现了一个更标准、更完整、更有效的领域自适应流水线。首先,我们提出了一种非对抗性渐进式颜色传递算法的输入图像级对齐。其次,我们设计了一个有效的无参数成本归一化层的内部特征级对齐。最后,一个高度相关的辅助任务,自我监督遮挡感知重建,以缩小输出空间的差距。我们的AdaStereo模型在多个立体声基准测试中实现了最先进的跨域性能,包括KITTI、Middlebury、ETH3D和DrivingStereo,甚至优于使用目标域地面实况进行微调的视差网络。

英文摘要:

Recently, records on stereo matching benchmarks are constantly broken by end-to-end disparity networks. However, the domain adaptation ability of these deep models is quite poor. Addressing such problem, we present a novel domain-adaptive pipeline called AdaStereo that aims to align multi-level representations for deep stereo matching networks. Compared to previous methods for adaptive stereo matching, our AdaStereo realizes a more standard, complete and effective domain adaptation pipeline. Firstly, we propose a non-adversarial progressive color transfer algorithm for input image-level alignment. Secondly, we design an efficient parameter-free cost normalization layer for internal feature-level alignment. Lastly, a highly related auxiliary task, self-supervised occlusion-aware reconstruction is presented to narrow down the gaps in output space. Our AdaStereo models achieve state-of-the-art cross-domain performance on multiple stereo benchmarks, including KITTI, Middlebury, ETH3D, and DrivingStereo, even outperforming disparity networks finetuned with target-domain ground-truths.
