基于差异颜色特性的自适应互补学习目标跟踪

Adaptive Complementary Learners with Diversified Color Attributes for Object Tracking

  • 摘要: 针对模板与像素互补学习(Staple)算法中梯度直方图(HOG)特征对目标形状与尺度变化表达能力较弱,以及不能自适应地进行模型融合与模型更新的问题,提出一种基于差异颜色特性的自适应互补学习目标跟踪算法.首先在HOG特征基础上,增加具有良好形状与尺度不变性的颜色名特征,使用此多通道特征计算位置滤波器的响应图;其次计算颜色直方图特征的特征响应图,依据2种响应图的峰值和平均峰相关能量(APCE)指标自适应地分配权重,得到最终融合响应图;最后根据融合响应图的峰值和APCE指标实现高置信度的模型更新.在OTB-13和OTB-15标准测试集上与5种主流的跟踪算法进行实验的结果表明,该算法在目标形变、尺度变化、光照变化、遮挡等情况下均具有较高的鲁棒性,其跟踪精度和成功率指标都优于Staple及其他主流的跟踪算法.

     

    Abstract: Histogram of oriented gradient(HOG)features used in the sum of template and pixel-wise learners(Staple)tracker have a poor ability of feature representation for deformation and scale variation.In addition,the fusion and updating of model can not be implemented adaptively.To solve these problems,an adaptive complementary learners with diversified color attributes for object tracking algorithm is proposed.Firstly,on the basis of HOG features,color names features with great invariance of shape and scale are added.The multi-channel features are used to calculate the response map of translation filter.Then,the response map of histogram is calculated by using color histogram features.The maximum peak and the average peak-to-correlation energy(APCE)of two response maps are used to obtain adaptively their weights of fusion.Finally,the high-confidence updating of model is implemented according to the maximum peak and the APCE of fused response map.Results compared with 5 state-of-the-art trackers are obtained on two benchmark datasets:OTB-13 and OTB-15.The experimental results demonstrate that the proposed algorithm performs high robustness in the scenarios with the interference of deformation,scale variation,illumination variation and occlusion.Moreover,the proposed algorithm performs favorably against Staple and other comparison algorithms in terms of tracking accuracy and success rate.
