Spatio-temporal video background inpainting

In this article we present a method for inpainting background parts of scene in videos. Such inpainted background view can be used for rendering stereoscopic views of high quality. Completion of background occluded by foreground object is necessary to solve the parallax occlusion. Known inpainting algorithms, e.g. Criminisi, 2004 [1] or Telea, 2004 [2] were primarily designed for inpainting of still images. However, frame-by-frame spatial inpainting of video inevitably leads to flickering. Our hybrid inpaint algorithm utilizes the fact that some parts of background can be seen in temporally close frames, and some can only be filled-in with spatial inpainting approaches. The algorithm considers foreground masks and video frames as input, performs motion analysis to determine areas where spatial and temporal inpainting should be used and then uses both approaches to find a plausible reconstruction of background. The resulting output is a video sequence with marked foreground object(s) removed.
