【摘要】 为了有效检测扩频信息的嵌入,提出一种基于局部二值模型(Local Binary Pattern,LBP)的视频隐写分析方法。利用视频序列的时空相关性建立三维正交模型,根据活动性分析剔除局部运动点,分别从XY、XT、YT三个平面提取其余点的LBP特征并进行直方图统计。与SPAM方法相比,文中提出的LBP模型不仅降低了局部运动的影响,更获得了较高的检测率。更多还原

【Abstract】 To complete the detection of spread spectrum information effectively,this paper proposes a video steganalysis scheme based on local binary patterns( Local Binary Pattern,LBP). Considering the spatial-temporal correlation of video sequences,it establishes three-dimensional orthogonal planes,eliminates points from motion regions based on motion analysis,extracts LBP features from XY,XT,YT planes respectively and then conducts histogram statistics of these three planes. Comparing with another scheme SPAM,this LBP model not only reduces the influence of local motion on detection precision,but also acquires a higher detection rate.更多还原
