多通道特征和择优并行更新的核相关滤波跟踪
Multi-Channel Feature and Preferred Parallel Update for Kernel Correlation Filter Tracking
摘要
Abstract
Aiming at the limitations of single features and insufficiencies update of target templates and feature appearance templates intraditional kernel tracker, a multi-channel feature and preferred parallel update for kernel correlation filter tracking is proposed. The multi-channel feature extraction method is adopted which means the upper branch uses the convolutional neural network to extract the depth features, and the lower branch combines the features of HOG and CN for training and tracking. A novel preferred parallel update method is proposed for updating the target templates and feature appearance templates. In the current frame, the maximum response value in both branches is considered as the optimal target position. In the next frame, the templates of the two branches are updated simultaneously with the parameters of the optimal position of the previous frame until the end of the tracking. The optimal parallel update of multiple branches makes up for the deficiency of single branch update. Experiments show that this algorithm can achieve more robust tracking result under different challenge factors.关键词
