中文摘要：

视觉跟踪在无人飞行器、移动机器人、智能监控等领域有着广泛的应用，但由于目标外观和环境的变化，以及背景干扰等因素的存在，使得复杂场景下的鲁棒实时的目标跟踪成为一项极具挑战性的任务．视觉注意是人类视觉信息处理过程中的一项重要的心理调节机制，在视觉注意的引导下，人类能够从众多的视觉信息中快速地选择那些最重要、最有用、与当前行为最相关的感兴趣的视觉信息，特别地，人类能够快速指向感兴趣的目标，从而可以轻松地实现对目标的稳定跟踪．因此，将视觉注意机制引入到复杂场景下的目标跟踪中，有利于实现更为稳定和接近于人类认知机制的视觉跟踪算法．本文旨在对引入了视觉注意机制的目标跟踪方法进行综述．首先，介绍了视觉注意的基本概念及其代表性的计算模型；其次，对视觉注意与跟踪的内在关系进行了阐述；然后，对引入视觉注意机制的目标跟踪方法进行归纳、总结和分类，对代表性的方法进行介绍和分析；最后，对该类方法的特点和优势进行了讨论，并对未来的研究趋势进行了展望．

英文摘要：

Visual tracking has been widely used in numerous applications, such as unmanned aerial vehicles, mobile robots and intelligent visual surveillance. Robust and real-time object tracking in complex scenes is a challenge task. Difficulties in tracking objects can arise due to changing appearance patterns of both the object and the environment, as well as factors such as background interference. Visual attention is one of the key mechanisms of visual perception which directs the processing resources to the visual data of the potentially most relevant, specially directs our gaze rapidly towards objects of interest in our visual environment and as a result humans can easily achieve stable object tracking. Therefore introducing the visual attention mechanism to the object tracking in complex scenes, will facilitate the realization of stable and humanoid tracking algorithms. This paper aims to review the state-of-the-art of visual attention based methods for tracking. Firstly, we introduce the basic concepts of visual attention and its representative computational models. Secondly, the relationship between visual attention and tracking is described. Thirdly, the attention-based visual tracking algorithms are classified into five categories and detailed descriptions of representative methods in each category are provided, and their pros and cons are examined. Finally, we highlight the advantages of attention-based tracking methods and provide insights for future.
