摘要: We present evolving time fronts, a new framework for spatiotemporal warping of video. The proposed is simple yet general, allowing large variety spatio-temporal warps to be specified in an intuitive manner. Specifically, we manipulate the flow video sequence by sweeping front surface through video’s aligned space-time volume. In this paper first introduce general framework, and then describe discuss several specific strategies evolution that have experimented with so far. These are demonstrated produce interesting useful operations on video, ranging from subtle timing changes eye-catching special effects, creation dynamic panoramic mosaics, parallax effects.
