针对传统的基于颜色特征的cam shift车辆跟踪算法易受到光照变化的干扰而无法有效地跟踪动态目标的问题,提出一种多特征融合的cam shift车辆跟踪算法.将局部二值模式(local binary pattern,LBP)纹理特征改进为局部三值模式(local ternary pattern,LTP)纹理特征,与HSV(hue,saturation,value)颜色特征相结合,建立目标模型,对运

提出一种多任务稳健主成分分析方法,用以结合多视觉特征实现运动目标分割.给定由多类型特征矩阵描述的视频数据,将它分解为低秩和稀疏部分,其中的稀疏部分对应于运动目标.该矩阵分解过程是一个凸优化问题,通过用ALM方法最小化核范数和2,1-范数的约束组合.与仅利用单类型特征的方法相比,本文提出的方法能够结合多类型特征,因此可获得更加精确可靠的结果.对HumanEva和Change Detection两个数

分析了非下采样Contourlet变换(nonsubsampled Contourlet transform,NSCT)和全变差模型的特点,提出将NSCT和全变差混合模型应用于医学图像去噪.首先,通过NSCT变换将含噪图像分解,运用Visu萎缩阈值将NSCT系数进行处理,得到初次去噪图像.然后,采用全变差模型对初次去噪图像进一步处理得到最终去噪图像.实验结果表明:该方法可以很好地保留图像细节,无论
