Title:
- Practical Eye Movement Model using Texture Synthesis
Abstract:
As humans we are especially sensitive to the appearance of the face, and on the face, the eyes are particularly important. In fact, in attempts to animate photo-realistic CG humans, the eyes are very often what destroys the illusion [Williams 2003]. The state of art in eye movement synthesis is the Eyes Alive model [Lee et al. 2002] that develops a custom statistical model specifically for eye movement. While its results are the best to date, the model is complex and one wonders if it could be improved by using additional or different statistics. In fact the problem of generating novel animation that captures the “character” of given training data is the same problem as texture synthesis. In this sketch we describe a practical eye movement model using non-parametric texture synthesis techniques ([Efros and Leung 1999]), simulating the eye gaze motion and eye blink motion simultaneously. This approach uses the data directly and without an intervening human- crafted statistical model, yet it produces results that appear as good or better than the more complex statistical model.
