【摘要】 基于视觉的目标跟踪技术有着广泛的实用价值。文章提出了一种基于纹理特征的人眼跟踪算法。该方法以纹理特征为模式特征,采用粒子滤波算法进行人眼跟踪,为了适应人眼的开闭两种状态,又采用了双状态模型。纹理特征具有较好稳定性,可以不受目标的外形和比例变化的影响;而粒子滤波算法可以快速和有效地进行跟踪。最后,给出了将该方法用于人眼跟踪的测试结果。更多还原

【Abstract】 This paper presents a new method of eyes tracing.Firstly,it uses texture spectrum as the input eigenvalue,which is picked up from texture character of eye images.Then it introduces a new Monte Carlo tracking technique.The use of a particle filter allows to better handle tracing in the background.Finally,in order to recover the state of the eyes(i.e.whether they are open or closed),it develops a dual-state model,and performs some experiments to make sure that the method works effective.更多还原
