Abstract: Joint video deblurring and stabilization techniques are described. In one or more implementations, a deblurring and stabilization module is configured to jointly deblur and stabilize a video by grouping video frames into spatial-neighboring frame clusters, and building local mesh homographies for video frames in each spatial-neighboring frame cluster.

Abstract: A simulated tracking shot is generated from an image sequence in which a foreground feature moves relative to a background during capturing of the image sequence. The background is artificially blurred in the simulated tracking shot in a spatially-invariant manner corresponding to foreground motion relative to the background during a time span of the image sequence. The foreground feature can be substantially unblurred relative to a reference image selected from the image sequence. A system to generate the simulated tracking shot can be configured to derive spatially invariant blur kernels for a background portion by reconstructing or estimating a 3-D space of the captured scene, placing virtual cameras along a foreground trajectory in the 3-D space, and projecting 3-D background points on to the virtual cameras.
Abstract translation: 在拍摄图像序列期间，前景特征相对于背景移动的图像序列生成模拟跟踪拍摄。 在图像序列的时间跨度期间，在相对于背景的前景运动相应于空间不变方式的模拟跟踪拍摄中，背景被人为地模糊。 相对于从图像序列中选择的参考图像，前景特征可以基本上未被翻转。 用于生成模拟跟踪镜头的系统可以被配置为通过重建或估计所捕获的场景的3-D空间，将虚拟相机沿着3D空间中的前景轨迹放置，从而为背景部分导出空间不变的模糊内核，以及 将3-D背景点投影到虚拟相机。
