抽象的。我们关注的是跟踪视频流中的感兴趣对象。我们提出了一种算法,该算法对遮挡、混乱颜色的存在、目标特征的突变和尺度变化具有较强的鲁棒性。我们在贝叶斯建模框架内开发了该算法。状态空间模型用于通过对跟踪系统的底层动态进行建模来捕获帧图像序列中的时间相关性。为了融合观测中的多线索信息,提出了贝叶斯模型平均(BMA)策略。在提议的框架中允许涉及任意数量的对象特征。每个特征代表一个待融合的信息源,并与一个观测模型相关联。采用粒子滤波方法进行状态推理。与相关方法相比,基于BMA的跟踪器具有较好的鲁棒性、可表现性和可理解性。
Abstract. We are concerned with tracking an object of interest in a video stream. We propose an algorithm that is robust against occlusion, the presence of confusing colors, abrupt changes in the object features and changes in scale. We develop the algorithm within a Bayesian modeling framework. The state-space model is used for capturing the temporal correlation in the sequence of frame images by modeling the underlying dynamics of the tracking system. The Bayesian model averaging (BMA) strategy is proposed for fusing multiclue information in the observations. Any number of object features is allowed to be involved in the proposed framework. Every feature represents one source of information to be fused and is associated with an observation model. The state inference is performed by employing the particle filter methods. In comparison with the related approaches, the BMA-based tracker is shown to have robustness, expressivity, and comprehensibility.
