摘要

摘要:
为解决基于时空正则项的目标跟踪算法(STRCF)在目标短时遮挡时定位精度低和目标旋转时尺度估计不准确的问题，该文提出了一种目标响应自适应的通道可靠性跟踪算法。该算法在目标模型训练时加入了目标响应正则项，通过在求解过程中更新理想目标响应函数，使得目标被短时遮挡后可重新跟踪目标；加入通道可靠性评价各特征通道的可靠性，提高了模型对目标的表达能力；将目标图像转换至对数极坐标系下训练尺度滤波器，提高在目标旋转时的尺度估计精度。实验结果表明，该文所提算法较STRCF在平均中心位置误差中降低了28.54个像素，在平均重叠率中提高了22.8%，在OTB2015数据集下成功率曲线下面积较STRCF提高了1.5%。

Abstract:
In order to solve the problems of lower precision of target location in short-term occlusion and inaccurate of scale estimation of target in rotation by Spatial-Temporal Regularized Correlation Filters (STRCF), an object tracking algorithm with channel reliability and target response adaptation is proposed in this paper. In this algorithm, target response regularization is added to train target model. By updating the ideal target response function in the process of solving model, the target can be tracked again after being occluded for a short time. The reliability of each feature channel is evaluated by coefficient of channel reliability, which can improves the model's expression of the target. Scale filters can be trained in log-polar coordinates to improve the accuracy of scale estimation when target is rotating. The experimental results show that the proposed algorithm reduces 28.54 pixels in the average center position error and improves the average overlap rate by 22.8% compared with STRCF.
