摘要:

在低光条件下获取的视频通常表现出运动模糊,这取决于对象相对于相机的运动。这不仅在视觉上令人不愉快,而且会妨碍进一步的处理。通过本文,我们首次展示了立体视频的可用性如何帮助完成具有挑战性的视频去模糊任务。我们利用3D场景流,即使在不利条件下也可以稳健地估计。我们超越了简单地确定对象运动的两种方式:首先,我们展示了如何分段刚性3D场景流表示允许通过局部单应性诱导准确的模糊内核。其次,我们利用估计的运动边界的3D场景流,以减轻振铃文物使用迭代加权方案。意识到3D对象的运动,我们的方法可以稳健地处理任意数量的独立移动的对象。我们展示了它的好处,在国家的最先进的视频去模糊渲染场景和真实视频使用定量和定性实验。

英文摘要:

Videos acquired in low-light conditions often exhibit motion blur, which depends on the motion of the objects relative to the camera. This is not only visually unpleasing, but can hamper further processing. With this paper we are the first to show how the availability of stereo video can aid the challenging video deblurring task. We leverage 3D scene flow, which can be estimated robustly even under adverse conditions. We go beyond simply determining the object motion in two ways: First, we show how a piecewise rigid 3D scene flow representation allows to induce accurate blur kernels via local homographies. Second, we exploit the estimated motion boundaries of the 3D scene flow to mitigate ringing artifacts using an iterative weighting scheme. Being aware of 3D object motion, our approach can deal robustly with an arbitrary number of independently moving objects. We demonstrate its benefit over state-of-the-art video deblurring using quantitative and qualitative experiments on rendered scenes and real videos.
