Capturing Eye Multi-Curve Spectrum

摘要

摘要: 该文给出了一种描述人眼运动及表情的多线谱表示及其获取的方法。该方法以人眼三维肌肉控制模型(3D-MCE)为基础,用一组归一化肌肉收缩量随时间变化的多线谱曲线来表示人眼运动及表情;给出了由单视频获取人眼多线谱的方法,通过跟踪人眼控制点的位移,计算肌肉收缩量,进而获得其随时间变化的曲线。实验结果表明,所获得曲线能较逼真地模拟人的眼部运动和部分表情。

Abstract: This paper presents a method of capturing multi-curve spectrums of eye movements and expressions. Based on 3D muscle controlled eye(3D-MCE)model, eye movements and expressions are described with a group of time-varying curves of normalized muscle contractions, called multi-curve spectrum. Multi-curve spectrum is obtained from single video with tracking specific control nodes and computing time-varying curves of muscle contractions. Realistic simulation results comprising eye movements and some expressions are genarated with multi-curve spectrums captured with this method.
