High-quality stereo and optical flow maps are essential for a multitude of tasks in visual media production, e.g. virtual camera navigation, disparity adaptation or scene editing. Rather than estimating stereo and optical flow separately, scene flow is a valid alternative since it combines both spatial and temporal information and recently surpassed the former two in terms of accuracy. However, since automated scene flow estimation is non-accurate in a number of situations, resulting rendering artifacts have to be corrected manually in each output frame, an elaborate and time-consuming task. We propose a novel workflow to edit the scene flow itself, catching the problem at its source and yielding a more flexible instrument for further processing. By integrating user edits in early stages of the optimization, we allow the use of approximate scribbles instead of accurate editing, thereby reducing interaction times. Our results show that editing the scene flow improves the quality of visual results considerably while requiring vastly less editing effort.

High quality dense image correspondence estimation between two images is an essential pre-requisite for view interpolation in visual media production. Due to the ill-posed nature of the problem, automated estimation approaches are prone to erroneous correspondences and subsequent quality degradation, e.g. in the presence of ambiguous movements that require human scene understanding to resolve. Where visually convincing results are essential, artifacts resulting from estimation errors must be repaired by hand with image editing tools. In this paper, we propose a new workflow alternative by fixing the correspondences instead of fixing the interpolated images. We combine realtime interactive correspondence display, multi-level user guidance and algorithmic subpixel precision to counteract failure cases of automated estimation algorithms. Our results show that already few interactions improve the visual quality considerably.
