视频目标跟踪问题分析         视频跟踪技术的主要目的是从复杂多变的的背景环境中准确提取相关的目标特征,准确地识别出跟踪目标,并且对目标的位置和姿态等信息精确地定位,为后续目标物体行为分析提供足够的数据.但是目前的绝大部分目标跟踪算法或多或少存在不少缺点,如:1)对目标的实时跟踪时,跟踪时间过长,目标容易丢失:2)当目标发生形变时(目标伪装.摄像平台变化导致),无法进行目标跟踪:3)当视频中目标消失(遮挡等)以后重新出现时,不能重新跟踪捕获目标,或出现混批: 4)有一些给定很少特定目标特征…

TLD算法回顾 TLD(Tracking-Learning-Detection)是英国萨里大学的一个捷克籍博士生Zdenek Kalal在其攻读博士学位期间提出的一种新的单目标长时间(long term tracking)跟踪算法.该算法与传统跟踪算法的显著区别在于将传统的跟踪算法和传统的检测算法相结合来解决被跟踪目标在被跟踪过程中发生的形变.部分遮挡等问题.同时,通过一种改进的在线学习机制不断更新跟踪模块的"显著特征点"和检测模块的目标模型及相关参数,从而使得跟踪效果更加稳定.鲁棒.…

摘要 近年来,深度学习方法在物体跟踪领域有不少成功应用,并逐渐在性能上超越传统方法.本文先对现有基于深度学习的目标跟踪算法进行了分类梳理,后续会分篇对各个算法进行详细描述. 看上方给出的3张图片,它们分别是同一个视频的第1,40,80帧.在第1帧给出一个跑步者的边框(bounding-box)之后,后续的第40帧,80帧,bounding-box依然准确圈出了同一个跑步者.以上展示的其实就是目标跟踪(visual object tracking)的过程.目标跟踪(特指单目标跟踪)是指:给出目标在…
