Abstract
We present a new representation for time-varying image data that allows for varying—and arbitrarily high—spatial and temporal res- olutions in different parts of a video sequence. The representation, called multiresolution video, is based on a sparse, hierarchical en- coding of the video data. We describe a number of operations for creating, viewing, and editing multiresolution sequences. These op- erations support a variety of applications: multiresolution playback, including motion-blurred "fast-forward" and "reverse"; constant- speed display; enhanced video scrubbing; and "video clip-art" edit- ing and compositing. The multiresolution representation requires little storage overhead, and the algorithms using the representation are both simple and efficient.Keywords
