Unstructured Video-Based Rendering: Interactive Exploration of Casually Captured Videos
This is an algorithm for navigating around a performance filmed as a "casual" multi-view video collection: real-world footage captured on handheld cameras by a few audience members. The challenge was to easily navigate in 3D, generating a video-based rendering of a performance filmed with widely separated cameras.
Dynamic Video Narratives
A dynamic video narrative is a compact representation of a video, which combines moving mosaics obtained from the frames of the video into a single, seamless interactive and playable image. Unlike image panoramas, dynamic video narratives allow in-place playback of videos in real time.
Video Tapestries With Continuous Temporal Zoom
A novel approach for summarizing video in the form of a multiscale image that is continuous in both the spatial domain and across the scale dimension: There are no hard borders between moments in time, and one can zoom smoothly into the image to reveal additional temporal details.
Motion-Based Video Retargeting With Optimized Crop-and-Warp
A video retargeting method that achieves high-quality resizing to arbitrary aspect ratios for complex videos containing diverse cameras and dynamic motions. The method combines novel cropping and warping operators, where cropping removes temporally repetitive contents, and warping utilizes available homogeneous regions to mask deformations while preserving motion.
