摘要:

针对视觉跟踪中的遮挡问题,提出了一种遮挡感知的跟踪算法。该算法根据目标的像素分布,通过聚类将目标分割成离散的图像块。为了避免跟踪器漂移到虚假目标,该算法提取的主导功能,如颜色直方图或直方图的梯度方向,从这些图像块,并使用它们作为线索进行跟踪。为了提高跟踪器的鲁棒性,该算法采用了一个隐式的空间结构之间的这些补丁作为跟踪的另一个线索,然后,该算法将这些组件的粒子滤波框架,这导致在一个强大的和精确的跟踪器。在不同分辨率的彩色图像序列上的实验结果表明,该跟踪器在处理视觉跟踪中的遮挡问题上优于比较算法。

英文摘要:

To overcome the problem of occlusion in visual tracking, this paper proposes an occlusion-aware tracking algorithm. The proposed algorithm divides the object into discrete image patches according to the pixel distribution of the object by means of clustering. To avoid the drifting of the tracker to false targets, the proposed algorithm extracts the dominant features, such as color histogram or histogram of oriented gradient orientation, from these image patches, and uses them as cues for tracking. To enhance the robustness of the tracker, the proposed algorithm employs an implicit spatial structure between these patches as another cue for tracking; Afterwards, the proposed algorithm incorporates these components into the particle filter framework, which results in a robust and precise tracker. Experimental results on color image sequences with different resolutions show that the proposed tracker outperforms the comparison algorithms on handling occlusion in visual tracking.
