Trifocal motion modeling for object-based video compression and manipulation
1998
IEEE transactions on circuits and systems for video technology (Print)
Following a brief overview of two-dimensional (2-D) parametric motion models commonly used in video manipulation and compression, we introduce trifocal transfer, which is an image-based scene representation used in computer vision, as a motion compensation method that uses three frames at a time to implicitly capture camera/scene motion and scene depth. Trifocal transfer requires a trifocal tensor that is computed by matching image features across three views and a dense correspondence between
