Anti-occlusion Tracking Method for Satellite Videos Based on Improved Correlation Filter

中文摘要英文摘要

卫星视频中的目标存在背景复杂、尺寸较小、容易受遮挡等问题,这将影响跟踪的准确性,甚至导致跟踪失败.提出了用改进的核相关滤波算法来解决卫星视频中目标遮挡问题,并对目标进行有效跟踪.该算法通过提取目标的HOG特征、LBP特征和SIFT特征共同描述目标,并以融合特征减少背景变化的影响.提出自适应卡尔曼滤波算法解决跟踪过程中目标被遮挡的问题,通过ITCI值判断目标是否被遮挡,并对被遮挡的目标进行位置预测,选用核相关滤波算法以满足跟踪的实时性和准确性.实验结果表明,改进的核相关滤波算法解决了目标遮挡问题,对目标背景变化有较好表现,同时跟踪的精度和成功率也有很大提高.

Some target tracking problems such as complex background,small size and easy to be occluded in satellite videos will affect the accuracy of tracking and even lead to tracking failure.Therefore,an improved kernel correlation filtering algorithm is proposed to solve the problem of target occlusion in satellite videos and to track the target effectively.The algorithm describes the target collectively by extracting the HOG features,LBP features and SIFT features of the target,and reduces the impact of background changes by using the fusion features.An adaptive Kalman filtering algorithm is proposed to solve the problem of target occlusion in the tracking process.The ITCI value is used to determine whether the target is occluded,and the position of the occluded target is predicted.The kernel correlation filtering algorithm is selected to meet the requirement of the real-time and accuracy of tracking.The experimental results show that the improved kernel correlation filtering algorithm solves the problem of target occlusion,performs better under the change of target background,and while improves the tracking accuracy and success rate greatly.
