说明：  本文提出一种复杂条件下基于子空间梯度方向直方图跟踪的方法, 实验结果表明,该方法能够在光照变化、噪声干扰、模糊、目标姿态和尺度改变,以及部分遮挡等恶劣条件下实现准确跟踪,比传统的跟踪方法具有更高的跟踪精度和跟踪鲁棒性,能够满足地面侦察任务在多种复杂条件下对感兴趣目标进行准确跟踪的需求
(In this paper, under the conditions of a complex gradient direction histogram based on subspace tracking method, experimental results show that the method can change the lighting, noise, blur, Pose and scale changes and partial occlusion and other adverse conditions to achieve accurate tracking than the traditional tracking method is more robust tracking accuracy and tracking, ground reconnaissance mission to meet the complex conditions in a variety of targets of interest demands accurate tracking)
