| 摘 要： | 提出了一种基于粒子滤波和层级形状描述的红外目标跟踪新方法。在粒子滤波理论框架下,观测概率模型的建立是影响红外目标跟踪性能的重要因素,而红外目标描述是建立观测概率模型的基础。针对红外成像特性,以梯度直方图和空域金字塔技术为基础,建立层级梯度直方图,实现红外目标的层级形状描述。通过计算参考目标的层级梯度直方图与目标样本的层级梯度直方图之间的Bhattacharyya距离,建立观测概率模型。两种不同场景特性的红外目标跟踪实验和对比实验分析都表明该方法是有效的、稳健的。

| Abstract: | A novel method for infrared target tracking is proposed based on particle filtering and hierarchical shape representation.Under the theory framework of particle filtering,the establishment of observation probability models is an important factor affecting the infrared target tracking performance.Infrared target representation is the foundation to build observation probability models.For the characteristics of infrared imaging,the hierarchical histogram of gradient and spatial pyramid technologies are applie... |
