论文摘要
立体声图像(包含左右视图差异图像)最近用于求解低视觉任务,例如降雨和超分辨率。立体声图像恢复方法通常通过隐式或显式地学习双重视图之间的差异通常比单眼方法获得更好的性能。但是,现有的立体降雨方法仍然无法充分利用两种观点之间的互补信息,我们发现这是因为:1)降雨条纹在方向和密度上具有更复杂的分布,这严重损害了互补信息,并带来了更大的挑战; 2)由于两种视图之间的特征的不完善融合机制,差异估计不够准确。 To overcome such limitations, we propose a new \underline{Stereo} \underline{I}mage \underline{R}ain \underline{R}emoval method (StereoIRR) via sufficient interaction between two views, which incorporates: 1) a new Dual-view Mutual Attention (DMA) mechanism which generates mutual attention maps by taking left and right views as key information for each other to促进跨视图融合; 2)由基本块和双视图相互关注构建的远距离和跨视图相互作用,可以减轻雨水对互补信息的不利影响,以帮助立体声图像的特征以获得远距离和跨视图的交互和融合。值得注意的是,立体声欧元在几个数据集上的其他相关单眼和立体图像去除方法的表现。我们的代码和数据集将发布。
Stereo images, containing left and right view images with disparity, are utilized in solving low-vision tasks recently, e.g., rain removal and super-resolution. Stereo image restoration methods usually obtain better performance than monocular methods by learning the disparity between dual views either implicitly or explicitly. However, existing stereo rain removal methods still cannot make full use of the complementary information between two views, and we find it is because: 1) the rain streaks have more complex distributions in directions and densities, which severely damage the complementary information and pose greater challenges; 2) the disparity estimation is not accurate enough due to the imperfect fusion mechanism for the features between two views. To overcome such limitations, we propose a new \underline{Stereo} \underline{I}mage \underline{R}ain \underline{R}emoval method (StereoIRR) via sufficient interaction between two views, which incorporates: 1) a new Dual-view Mutual Attention (DMA) mechanism which generates mutual attention maps by taking left and right views as key information for each other to facilitate cross-view feature fusion; 2) a long-range and cross-view interaction, which is constructed with basic blocks and dual-view mutual attention, can alleviate the adverse effect of rain on complementary information to help the features of stereo images to get long-range and cross-view interaction and fusion. Notably, StereoIRR outperforms other related monocular and stereo image rain removal methods on several datasets. Our codes and datasets will be released.
