Multiresolution video
Adam Finkelstein, Charles E. Jacobs, David Salesin · 1996
We present a new representation for time-varying image data that allows for varying-and arbitrarily high-spatial and temporal resolutions in different parts of a video sequence.The representation, called multiresolution video, is based on a sparse, hierarchical encoding of the video data.We describe a number of operations for creating, viewing, and editing multiresolution sequences.These operations support a variety of applications: multiresolution playback, including motion-blurred "fast-forward" and "reverse"; constantspeed display; enhanced video scrubbing; and "video clip-art" editing and compositing.The multiresolution representation requires little storage overhead, and the algorithms using the representation are both simple and efficient.
