摘要:

在本文中,我们提出了一个简单而有效的布尔地图为基础的表示,利用连接线索的视觉跟踪。我们描述了一个目标对象与直方图的方向梯度和原始的颜色特征,其中每一个是由一组布尔映射的特点是通过均匀的阈值产生的值。布尔映射有效地编码具有不同粒度的目标的多尺度连接线索。细粒度的布尔映射捕捉空间结构的细节,是有效的精确的目标定位,而粗粒度的编码的全局形状信息,是强大的大目标外观变化。最后,所有的布尔映射一起形成一个强大的表示,可以近似由一个明确的特征映射的交集内核,这是一个逻辑回归分类器与在线更新,并估计目标位置的粒子滤波框架内。所提出的表示方案是计算效率高,有利于实现良好的性能方面的准确性和鲁棒性对国家的最先进的跟踪方法在一个大的基准数据集的50个图像序列。

英文摘要:

In this paper, we present a simple yet effective Boolean map based representation that exploits connectivity cues for visual tracking. We describe a target object with histogram of oriented gradients and raw color features, of which each one is characterized by a set of Boolean maps generated by uniformly thresholding their values. The Boolean maps effectively encode multi-scale connectivity cues of the target with different granularities. The fine-grained Boolean maps capture spatially structural details that are effective for precise target localization while the coarse-grained ones encode global shape information that are robust to large target appearance variations. Finally, all the Boolean maps form together a robust representation that can be approximated by an explicit feature map of the intersection kernel, which is fed into a logistic regression classifier with online update, and the target location is estimated within a particle filter framework. The proposed representation scheme is computationally efficient and facilitates achieving favorable performance in terms of accuracy and robustness against the state-of-the-art tracking methods on a large benchmark dataset of 50 image sequences.
