【摘要】 由目标跟踪的数学模型得出,影响目标跟踪性能的三个主要因素为目标状态转移模型、滤波算法和目标建模技术。对目标建模技术进行了综述和分析,分别从特征选择、特征的统计建模和相似性度量三个方面进行了阐述。以畸变不变性、目标/背景分辨能力作为性能评价手段定性地比较了国内外文献中提出的多种目标表征模型。指出了目标跟踪中目标表征模型自适应选择的研究方向。更多还原

【Abstract】 From mathematical model of target tracking,Performance of target tracking is impacted by three main factors of object state transition model,filtering algorithm and object modeling technique.The object modeling is mainly summarized and analysized,then the feature selection,statistical model of feature and similarity measuring are described.Distortion invariant and discrimination ability for target/background are regarded as the performance evaluation method to compare numerous object presentation models qualitatively proposed in domestic and foreign literatures.The research direction on adaptive selection of object representation model in target tracking is presented.更多还原
