Joint Stabilization And Direction Of 360° Videos, Chengzhou Tang, Oliver Wang, Feng Liu, Ping Tan
Computer Science Faculty Publications and Presentations
Three-hundred-sixty-degree (360°) video provides an immersive experience for viewers, allowing them to freely explore the world by turning their head. However, creating high-quality 360° video content can be challenging, as viewers may miss important events by looking in the wrong direction, or they may see things that ruin the immersion, such as stitching artifacts and the film crew. We take advantage of the fact that not all directions are equally likely to be observed; most viewers are more likely to see content located at “true north,” i.e., in front of them, due to ergonomic constraints. We therefore propose 360° video …
Context-Aware Synthesis For Video Frame Interpolation, Simon Niklaus, Feng Liu
Context-Aware Synthesis For Video Frame Interpolation, Simon Niklaus, Feng Liu
Computer Science Faculty Publications and Presentations
Video frame interpolation algorithms typically estimate optical flow or its variations and then use it to guide the synthesis of an intermediate frame between two consecutive original frames. To handle challenges like occlusion, bidirectional flow between the two input frames is often estimated and used to warp and blend the input frames. However, how to effectively blend the two warped frames still remains a challenging problem. This paper presents a context-aware synthesis approach that warps not only the input frames but also their pixel-wise contextual information and uses them to interpolate a high-quality intermediate frame. Specifically, we first use a …
