摘要: 近年来,结合深度特征的相关滤波算法由于较高的跟踪精度在视觉跟踪领域受到了广泛的关注.对训练样本的周期性假设一方面提高了计算效率,但是也引入了边界效应,限制了算法性能的进一步提升.通过对深度特征表达能力的深入挖掘,本文提出了一种新的跟踪框架.由于深层特征具有良好的语义信息,选取VGG网络第五层卷积特征提取目标的空间可靠区域,将该区域信息用于对样本进行裁剪并引入目标函数,建立空间约束模型,接着采用ADMM算法进行迭代求解.为了进一步提高算法的长时跟踪能力,提出一种简单有效的遮挡判断方法.实验结果表明,所提出的算法在跟踪精度和成功率上优于大多数先进的算法.

Abstract: In recent years,the correlation filter based algorithm combined with deep features has received extensive attention.The period assumption of the training samples improves the computational efficiency,but also introduces the boundary effect,which limits the further improvement of the tracking performance.By exploring the deep feature representation ability,a new tracking framework is proposed.Since the deep features have good semantic information,the fifth layer convolution feature of VGG network is used to extract the spatially reliable region of the target,and the region information is introduced into the objective function to establish a spatial constraint model.Then iteratively solved by ADMM algorithm.In order to further improve the long-time tracking ability,a simple and effective method of occlusion detection is proposed.Experimental results show that the proposed algorithm outperforms most advanced algorithms in tracking accuracy and success rate.
