多视角特征融合的鲁棒的目标跟踪方法

Robust Target Tracking Method Based on Multi-view Features Fusion

  • 摘要: 针对传统目标追踪模型中单一特征对目标描述不准确、不充分,产生噪声样本作为目标参与后续计算出现跟踪漂移等问题,提出多视角特征融合的鲁棒目标跟踪方法.首先利用迭代求解单一特征训练误差和最小的方式实现样本多视角特征自动征融合与描述,引入高次幂系数避免模型退化,并利用核方法保证维度不同特征的融合;其次将模型进一步拓展为增量学习方法,实现目标检测阶段判别模型实时构建,并获得当前帧候选目标样本集;最后根据候选目标样本集与判别边界位置关系,选择最优样本作为当前帧目标样本并利用指数函数增加样本间区分度.在20个具有挑战的图像序列上对文中方法进行验证,实验结果表明,该方法与目前流行的目标跟踪模型比较,获得了较好的效果与较高的鲁棒性.

     

    Abstract: Traditional tracking methods utilizing the single view feature to describe samples are inaccuracy and insufficiency.Therefore,these methods will result in some problems,for instance,the noise sample as the target object usually products the drifting in the tracking processing.For above problems,we propose a robust tracking model based on multi-view features fusion.Firstly,the proposed model achieves the minimum of the training error sum of all single features by iteration solving,and introduces combinatorial coefficients with higher powers to avoid degradation of the model.Moreover,we use the kernel function to fusion multi-view features of different dimensions.Secondly,in order to achieve the real-time building of the discrimination,we improve the model to the incremental method,and obtain the candidate set of target samples at the current frame.Finally,according to the position relationship between the candidate set and the decision boundary we obtain the most suitable sample as the target object,and the exponential function is used to strengthen the differentiation between the samples.According to the tracking performance in 20 image sequences with challenging,the proposed method achieves more effective and robust performance than popular tracking methods.
