Automated Video Looping With Progressive Dynamism

A concise spectrum of looping videos with varying levels of dynamism to enable interactive control over the amount of scene activity in background images and slideshows, based on personal taste or mood. The representation also segments the scene into independently looping regions, allowing further local control.

Bundled Camera Paths for Video Stabilization

A new 2D video stabilization method with a bundled-camera-paths model. The proposed method uses a mesh-based, spatially variant motion representation and an adaptive, space-time path optimization. It can fundamentally handle parallax and rolling-shutter effects without requiring long-feature trajectories or sparse 3D reconstruction.

Phase-Based Video Motion Processing

An approach for processing motion in videos based on analyzing local phase variations in complex-valued steerable pyramids, which improves significantly the results for motion magnification of our previous Eulerian method and introduces new capabilities.

Depth Synthesis and Local Warps for Plausible Image‐Based Navigation

This method of image-based rendering for urban scenes uses shape-preserving superpixel warps to complement 3D reconstruction by filling "plausible" depth in poorly reconstructed regions. The superpixel representation provides correct occlusions, and the shape-preserving warp alleviates rendering artifacts. The paper demonstrates pleasing free-viewpoint navigation on challenging scenes.
