We propose ‘evolving time fronts’, a new framework for spatio-temporal warping of video. The proposed framework is simple yet general, allowing a large variety of spatio-temporal warps to be specified in an intuitive manner. Specifically, we manipulate the time flow of a video sequence by sweeping an evolving ‘time front’ surface through the video’s aligned space-time volume.
