基于粒子滤波的多模板笔尖跟踪算法

Multi-templates Pen Tip Tracking Algorithm Based on Particle Filtering

针对笔尖在书写过程中易受光线、阴影和速度过快等不利因素影响的问题,提出一种基于粒子滤波的多模板笔尖跟踪算法,利用笔尖的形状特点检测定位笔尖,在粒子滤波的基础上融合多模板匹配进行笔尖跟踪。实验结果表明,该算法在采用较少粒子数的条件下,可以避免不利因素的影响,取得较好的跟踪效果。

For overcoming the lighting,shadow and excessive speed effects during the writing process,this paper proposes a multi-templates pen tip tracking algorithm based on particle filtering.Pen tip is detected according to its shape,and the pen tip tracking is implemented by particle filtering with multi-templates.Experimental results show that this algorithm is effective using fewer particles and the effects of adverse factors can be avoided to some extent.
