针对跟踪雷达的三种常见欺骗干扰,提出了一种基于积谱矩阵(SPM)局部二值模式(LBP)的识别算法。首先,计算雷达接收信号不同脉冲重复周期(PRI)的积谱,并将其按照频域和慢时域排列成一个二维积谱矩阵。然后,将图像处理的纹理特征引入到欺骗干扰识别的算法中,采用局部二值模式提取二维积谱矩阵的灰度图像特征。最后,通过仿真实验验证了算法的正确性,当雷达接收信号的信噪比(SNR)大于5 dB时,该欺骗干扰识别算法的平均识别概率优于90%。  相似文献

现有的基于稀疏表示的人脸识别算法在识别前需要将彩色人脸图像转换成灰度人脸图像,这样虽然提高了运算速度,但忽视了不同色彩通道数据本身所包含的信息及它们之间的相关性。为了利用不同通道间相关性,基于标签一致的K奇异值分解(LC-KSVD)字典学习算法,提出了一种适用于彩色图像人脸识别的字典学习算法。该算法将RGB通道数据顺序排列成列向量,并在稀疏编码的环节中,对正交匹配追踪(OMP)算法的内积计算准则进行修正,以此提高字典原子的色彩表达能力。在彩色人脸数据库上进行实验,结果表明:所提出的字典学习算法能够有效地提高识别率。  相似文献
