Line drawing, leap years, and Euclid
Bresenham's algorithm minimizes error in drawing lines on integer grid points; leap year calculations, surprisingly, are a generalization. We compare the two calculations, exp...

MPEG-4 Compatible Faces from Orthogonal Photos
MPEG-4 is scheduled to become an International Standard in March 1999. This paper demonstrates an experiment for a virtual cloning method and animation system, which is compatible...

Speech Driven Facial Animation using a Hidden Markov Coarticulation Model
We present a hierarchical image based facial model which is driven from speech. It incorporates a novel modelling and synthesis algorithm for learning and producing coarticulated ...

Using Model-Driven Bundle-Adjustment to Model Heads from Raw Video Sequences
We show that we can effectively and automatically fit a complex facial animation model to uncalibrated image sequences. Our approach is based on model-driven bundleadjustment foll...
